Disk-Space Requirements for Internet Explorer 5.5 Service Pack 1
  and Internet Tools 
------------------------------------------------------------------
Internet Explorer 5.5 Service Pack 1 and Internet Tools Setup installs 
the majority of its files on the drive where the Windows operating 
system is installed, regardless of the installation location you 
chose. To free up space on your hard disk in order to meet the 
Internet Explorer 5.5 Service Pack 1 disk-space installation requirements, 
you must free up space on the drive where the Windows operating 
system is installed.


SETUP
=====

Installing Internet Explorer 5.5 Service Pack 1 and Internet Tools
------------------------------------------------------------------
Whether you choose to install over the network or download the 
installation files to your hard disk, some or all of the Setup 
files are copied to your hard disk. This allows you to reinstall 
more quickly if necessary. If you want to reclaim the disk space, 
you can remove the Setup directory as follows:

1. In Control Panel, double-click Add/Remove Programs, and then click 
   Internet Explorer 5.5 Service Pack 1 and Internet Tools. 

2. Click Add/Remove, make sure the check box for Restore the Previous 
   Windows Configuration is selected, and then click Advanced.

3. Click the option named Remove Folder Containing Windows Update Setup 
   Files, and then click OK. 

4. When asked whether you want to continue, click Yes.

5. Click OK in the next dialog boxes.

You cannot install Internet Explorer 5.5 Service Pack 1 and Internet Tools 
to or run it from a network drive. However, you can download it to a network 
drive. To do this, you must map the network drive to a drive letter on 
your computer; you cannot download Internet Explorer 5.5 to a UNC path.


Running Internet Explorer 5.5 Service Pack 1 on Microsoft Windows NT 4.0
------------------------------------------------------------------------

 Note
 You must have administrative privileges to install 
 and uninstall this program on Windows NT. This includes 
 having administrative privileges the first time you 
 start your computer after installing or uninstalling.

You must restart your computer after installing Internet Explorer 
5.5 and Internet Tools. This is also true for some add-on 
components.

For corporate deployment on computers running Windows NT 4.0, 
make sure you have the following free registry space:

- If you are upgrading from Internet Explorer 2.0 or 
  Internet Explorer 3.x: at least 4 MB
- If you are upgrading from Internet Explorer 4.x:
  at least 2.5 MB 

If you're running Internet Explorer 5.5 Service Pack 1 on Windows NT 4.0, 
you must set user permissions to Full Control for the Temporary 
Internet Files folder (cache). The user must have write permission 
so that files can be stored in the Temporary Internet Files folder.

If you must reinstall Windows NT 4.0 Service Pack 3 (SP3) after you 
install Internet Explorer 5.5 Service Pack 1 and Internet Tools, you must 
specify when prompted that you do not want it to overwrite any files that 
are newer. After SP3 is reinstalled, carry out the following steps 
to update the registry:

1. Click the Start button, and then click Run.

2. Type the following: regsvr32 rsabase.dll


Installing Windows NT 4.0 Service Packs over Internet Explorer 5.5 
------------------------------------------------------------------
If you reinstall a Windows NT 4.0 Service Pack after Internet 
Explorer 5.5 Service Pack 1 and Internet Tools is installed on your 
computer, some components will need to be re-registered. To do this, carry 
out the following steps:

1. In Control Panel, double-click Add/Remove Programs.

2. On the Install/Uninstall tab, click Microsoft Internet Explorer 
   5.5 Service Pack 1 and Internet Tools.

3. Click Add/Remove.

4. Click Repair Internet Explorer, and then click OK.

5. After the repair operation is complete, restart your computer.


Installing over Windows 2000 Releases
-------------------------------------
Typical and Full installations are not currently available for Windows 2000. 
Internet Explorer 5.5 Service Pack 1 will install a minimal set of files into 
your computer; this includes the Internet Explorer 5.5 Service Pack 1 Web browser 
and scripting support. Other components such as Outlook(R) Express are not 
available for Windows 2000 at this time.


Uninstall Internet Explorer 5.5 Service Pack 1 Before Upgrading to 
  Windows 2000
-------------------------------------------------------------------
Windows 2000 contains an earlier version of Internet Explorer components.
When upgrading from Windows 95, Windows 98, or Windows NT to Windows 2000, 
we recommend that you uninstall Internet Explorer 5.5 Service Pack 1 before 
the upgrade. 


Downloading Internet Explorer by Using Third-Party Download Manager
-------------------------------------------------------------------
During the Internet Explorer 5.5 Service Pack 1 and Internet Tools installation, 
Setup must download components from the Internet. If you are using third-party 
download managers (for example, Netzip or GetRight) they will intercept 
the download request. This will cause Setup to stop. To prevent this
from occurring, first disable third-party download managers, and then run Setup.


High Encryption Support For Internet Explorer 5.5 Service Pack 1 
----------------------------------------------------------------
High Encryption components are available on Windows 95, Windows 98,
Windows 98 Second Edition, Windows Me, and Windows NT 4.0. To obtain 
high-encryption support for Windows 2000, please visit Windows Update or
http://www.microsoft.com/windows2000/downloads/recommended/encryption/default.asp


Enhanced Encryption Strength
----------------------------
Internet Explorer 5.5 now ships with a standard encryption strength of 128 bits 
and supports the U.S. government standard for data encryption (DES). 128-bit 
Internet Explorer 5.5 is eligible for distribution to all users worldwide except 
in U.S.-embargoed destinations. For more information, visit the following Web site:
http://www.microsoft.com/exporting/


Running Internet Explorer 5.5 Service Pack 1 on a Dual-Boot Operating System
-----------------------------------------------------------------------------
If you are running Internet Explorer 5.5 Service Pack 1 on a computer that 
is set up to dual boot between two operating systems on the same partition 
(for example, Windows 95 and Windows NT 4.0), and you have configured 
the computer to share a single Program Files folder, you might have 
problems with add-on components. 

Also, when you uninstall an add-on component from either copy of 
Internet Explorer 5.5, it will be removed from both of them without 
updating the other operating system's installed components information. 

These problems occur because the add-on files are all stored in the 
shared Program Files folder, but information about installed add-on 
components is stored elsewhere.


Installing or Upgrading the Windows Desktop Update
--------------------------------------------------
To install or upgrade the Windows Desktop Update, you must install 
Internet Explorer 4.01 SP2 before you install Internet Explorer 5.5 
and Internet Tools. 

If you have already installed Internet Explorer 5.5 and would like to 
install the Windows Desktop Update, carry out the following steps:

1. Uninstall Internet Explorer 5.5 Service Pack 1 by using the procedure listed 
   later in this document.

2. If Internet Explorer 4.01 SP2 is not already installed on your computer, 
   install it.

3. Install the Windows Desktop Update by using Add/Remove Programs in Control 
   Panel.

4. Reinstall Internet Explorer 5.5 Service Pack 1 and Internet Tools.


Installing over Localized Windows 98 Arabic and Hebrew Releases
---------------------------------------------------------------
Windows 98 Arabic and Hebrew versions require the corresponding 
localized version of Internet Explorer 5.5. It is not possible to 
install the English version of Internet Explorer over the localized 
version of Windows 98. 

This restriction does not apply to localized versions of Windows 95 
or Windows NT 4.0. However, you cannot install localized Arabic or 
Hebrew Internet Explorer 5.5 Service Pack 1 over localized Windows 95 
(only English is supported). 


Installing Outlook Express 5.x on Windows Terminal Server
---------------------------------------------------------
Before installing Outlook Express 5.x on Windows Terminal Server, 
the administrator needs to set a compatibility flag in the registry 
in order for the Outlook Express 5.x Setup program to work correctly. 
To do this, carry out the following steps: 

1. Create this registry key: 

 HKEY_LOCAL_MACHINE\Microsoft\Windows NT\CurrentVersion\Terminal Server\
 Compatibility\Applications\setup50 

2. Set the following value under the new setup50 key (this value 
should be of type REG_DWORD): 

 Flags = 0x108


Installing on Windows 98 with Novell IPX/IP Client
--------------------------------------------------
If you are using Novell IPX/IP client with Windows 98, you might 
experience problems if you install Internet Explorer 5.5 and Internet 
Tools from the Internet. If Setup appears to become unresponsive, 
restart your computer. Setup will continue and finish normally. To 
work around this problem, try one of the following options:

- In Setup, select the Download Only option, and then run and install 
  Internet Explorer 5.5 Service Pack 1 normally.

- Install Internet Explorer 5.5 Service Pack 1 from a CD-ROM.


Uninstalling Internet Explorer 5.5 Service Pack 1 and Internet Tools
--------------------------------------------------------------------
You can uninstall Internet Explorer 5.5 Service Pack 1 and Internet Tools by 
carrying out the following steps:

1. In Control Panel, double-click Add/Remove Programs.

2. Click Microsoft Internet Explorer 5.5 Service Pack 1 and Internet Tools, 
   and then click Add/Remove.

3. Click Restore the Previous Windows Configuration, and then click OK.

4. Follow the instructions on the screen.


Uninstall for Previous Versions of Internet Explorer Unavailable
----------------------------------------------------------------
If you uninstall Internet Explorer 5.5 Service Pack 1, you will not be able 
to remove the browser that was installed prior to Internet Explorer 5.5.


Uninstalling Internet Explorer 5.5 Service Pack 1 Returns You to an Earlier 
  Version
---------------------------------------------------------------------------
When you install Internet Explorer 5.5 Service Pack 1, Setup examines your 
system for the presence of uninstall data that had been created by a previous 
installation. If Setup cannot find this data, it creates new uninstall data 
for later use.

If you previously upgraded from Internet Explorer 4.x to 5.0 or 5.01, you 
will have uninstall data that allows you to roll back to Internet Explorer 4.x. 
Unless you explicitly removed the uninstall data using Add/Remove Programs 
in Control Panel before upgrading to Internet Explorer 5.5 Service Pack 1, 
this data will be preserved. When you uninstall Internet Explorer 5.5 Service 
Pack 1, it will use the existing uninstall data and roll back to 
Internet Explorer 4.x.

The following chart lists the various upgrade scenarios and the 
Internet Explorer 5.5 uninstallation behavior that can occur in each case.

+-------------------------------------------------------------------------------------------+
| Previous Version                    | Uninstall Data | Uninstall Results                  | 
+-------------------------------------------------------------------------------------------+
| Internet Explorer 3.x               | n/a            | Internet Explorer 3.x              | 
+-------------------------------------------------------------------------------------------+
| Internet Explorer 4.x               | n/a            | Internet Explorer 4.x              | 
+-------------------------------------------------------------------------------------------+
| Internet Explorer 5                 | Exists         | Pre-Internet Explorer 5 version    | 
+-------------------------------------------------------------------------------------------+
| Internet Explorer 5                 | Doesn't exist  | Internet Explorer 5                | 
+-------------------------------------------------------------------------------------------+
| Windows 98 (Internet Explorer 4)    | n/a            | Windows 98 (Internet Explorer 4)   | 
+-------------------------------------------------------------------------------------------+
| Windows 98 SE (Internet Explorer 5) | n/a            | Windows 98 SE (Internet Explorer 5)| 
+-------------------------------------------------------------------------------------------+


Using Download only
-------------------
In Internet Explorer 5.5, if you select the Download Only option you will not 
be able to choose which components are downloaded and which are not. All the 
cabinet (.cab) files for a full installation for the operating system you 
choose are downloaded. There is no user interface in Windows 2000 to select 
Download Only. 

To perform a Download Only on Windows 2000, see the following article in 
the Microsoft Knowledge Base:
http://support.microsoft.com/support/kb/articles/q257/2/49.asp


Windows 2000 Upgrade Exception Pack
-----------------------------------
Internet Explorer 5.5 Service Pack 1 includes a component called the 
Windows 2000 Upgrade Exception Pack.  This purpose of the Exception Pack is 
to downgrade Internet Explorer 5.5 Service Pack 1 in preparation for upgrade 
to Windows 2000. Until the computer is upgraded to Windows 2000, the 
Exception Pack is not invoked.  During the installation of Windows 2000, the 
Exception Pack removes Internet Explorer 5.5 Service Pack 1 registry keys 
that are no longer needed or contrary to entries created by Windows 2000; 
this ensures a problem-free upgrade.


Outlook Express Removed After Uninstalling Internet Explorer
------------------------------------------------------------
After you uninstall Internet Explorer and Outlook Express 5.01 or 
Outlook Express 5.5 from a computer running Windows 98 Second Edition, 
the previous version of Outlook Express is not restored.  For more 
information about this issue, please see the following article in the 
Microsoft Knowledge Base:
http://support.microsoft.com/support/kb/articles/q245/3/16.asp


MUI Settings when Upgrading to Internet Explorer 5.5 Service Pack 1
-------------------------------------------------------------------
After upgrading to Internet Explorer 5.5 Service Pack 1 MUI Menu items may 
display in English.  The language in question may not properly appear.  This 
can fixed by reinstalling applicable MUI files.


=================
ADDITIONAL ISSUES
=================

FTP User Interface and Functionality
------------------------------------
If you discover an issue in the FTP user interface that blocks FTP 
functionality, you can turn off this feature on the Advanced tab in the 
Internet Options dialog box.
 
The following functionality is not supported:
 
- Internet connection via CERN or Web proxy servers.
- Connecting to VAX or VMS FTP servers.
- Using the browser from within a separate application or service.
- Copying from server to server.
- Drag-and-drop or copy-and-paste functionality from an FTP 
  server is supported only on Windows 2000, Windows Me, and later.


Font Display Issues
-------------------
If you run a non-Asian language version of Windows NT 4.0 and 
you have installed many large fonts, the system's ability to use 
those fonts may be exceeded. If Asian language Web pages are not 
displayed correctly, install Windows NT 4.0 Service Pack 5.


Non-English Characters in URLs and Queries
------------------------------------------
Internet Explorer 5.5 uses a new standard to transmit non-English addresses 
(URLs) to the server. URLs are now encoded in a character-encoding standard 
named UTF-8. If the server is running Windows 2000, the URLs will work as 
expected. Many servers cannot process URLs encoded in UTF-8. To use 
non-English characters in URLs with these servers, carry out the following 
steps:
 
1. On the Tools menu in the browser, click Internet Options.

2. Click the Advanced tab.

3. Under Browsing, clear the Always Send URLs As UTF-8 check box.
 
The query part of URLs is transmitted in a form fully compatible 
with Internet Explorer 4 and above.


Internet Explorer 4.x Compatibility Mode
----------------------------------------
The Internet Explorer 4.x compatibility option is useful to Web 
developers who want to view and test their Web sites on different 
versions of Internet Explorer, using the same computer. You might
not be able to change all settings for the browser while in this 
mode. When using the compatibility option, you should change 
Internet options via Control Panel, not through the Internet Options 
command on the browser's Tools menu.


Uninstalling Outlook Express 5.x 
--------------------------------
If you uninstall Outlook Express 5.x and you were previously running 
Microsoft Internet Mail and News, you will be able to see only the 
messages you received using Internet Mail and News. To view 
Outlook Express 5.x messages, you must reinstall Outlook Express 5.x. 

If you uninstall Outlook Express 5.x and you were previously 
running Outlook Express 4.x, you can view your Outlook Express 5.x 
messages in version 4.x by carrying out the following steps: 

1. On the File menu in Outlook Express, click Import, and then click Messages.

2. In the list of programs, click Microsoft Outlook Express 5.

3. Follow the instructions on your screen.


Radio Toolbar
-------------
Internet Explorer 5.5 Service Pack 1 includes a Radio toolbar that allows 
streaming radio playback over the Internet. By default, the toolbar is not 
displayed when the browser is started. To display the toolbar whenever the 
browser is started, carry out the following steps:

1. On the Tools menu in the browser, click Internet Options.

2. Click the Advanced tab.

3. Under Multimedia, select the check box labeled Always Show 
   Internet Explorer (5.0 or Later) Radio Bar.


Changing the Language of Menus and Dialog Boxes
-----------------------------------------------
Changing the language used in menus and dialog boxes might not work 
with all display adapters. If you see blank menus or dialog boxes 
after changing the language, try either of the following options:

- Change the resolution of your display adapter.
- Upgrade the driver for your display adapter to a newer 
  version. For information about updated drivers, contact 
  the manufacturer of your display adapter.


AutoComplete Options
--------------------
If you do not want AutoComplete to suggest matches for certain 
sensitive items you have previously entered, you have several 
options:

- To delete a specific AutoComplete entry, highlight it in the 
  AutoComplete drop-down list, and then press DELETE.

- To delete a user name/password combination on a login page, 
  delete the user name; the password will be deleted with it.

- To clear all form or password information, do the following:

  1. On the Tools menu in the browser, click Internet Options.

  2. Click the Content tab. 

  3. Click AutoComplete, and then click Clear Forms or Clear 
     Passwords.


Operating System Limitations for Character Rotation in Vertical Text 
--------------------------------------------------------------------
When working with vertical text layout, full-width (East Asian 
language) characters will be displayed with upright orientation 
only on East Asian versions of Windows 95, Windows 98, Windows Me, 
and Windows NT 4.0 Operating Systems. All language versions of 
Windows 2000 provide this support. 


Security Settings
-----------------
The settings for the security levels of the Web content zones 
have changed for Internet Explorer 5.5 and might no longer be 
consistent with those in previous versions of Internet Explorer.  
If you upgrade from a previous version of Internet Explorer, 
Setup will save your previous security settings and transfer 
them to Internet Explorer 5.5 as a Custom Security Level.


Contacts Missing in Address Book After Uninstalling Windows Me
--------------------------------------------------------------
When uninstalling Windows Millennium Edition (Me), contacts that 
you added while using Windows Me might be missing from the Windows 
Address Book. When you upgrade to Windows Me, the Windows Address 
Book data file is backed up. During the uninstallation process, 
the backup copy of the data file is restored, overwriting any data 
that had been added in Windows Me. To preserve any contacts made 
in Windows Me, back up the .wab file(s) before uninstalling.  
After Windows Me has been removed, the .wab file(s) can be 
recopied back into place and used if Internet Explorer 5.01 
or greater is installed.


Outlook Express Title Screen Does Not Match Version
---------------------------------------------------
When you start Outlook Express, the title screen indicates that 
the product is "Microsoft Outlook Express 5" even though you 
installed a later version of Outlook Express. The title screen 
reflects only major product versions, such as version 4 or 5. 
Versions 5.01 and 5.5 are considered minor upgrades.


Active Scripting Enabled after Upgrade from Beta Versions of 
Internet Explorer 5.5 Service Pack 1 and Internet Tools
-------------------------------------------------------------
If you are using a beta version of Internet Explorer 5.5 Service Pack 1
and Internet Tools on Windows 2000, you may want to check your security 
settings for the Restricted zone. "Active Scripting" is disabled by 
default for this zone in the released version of Internet Explorer 5.5 
Service Pack 1 and Internet Tools. However, beta users might find this 
setting enabled after installing the released version. 

To return this setting to its proper value in Internet Explorer 5.5,
use the following steps:

1. On the Tools menu, click Internet Options.

2. Click the Security tab, click Restricted Sites, and then click 
   Default Level.


=================
DEVELOPER'S NOTES
=================

New Language Features in JScript and VBScript
---------------------------------------------
Internet Explorer 5.5 Service Pack 1 ships with new versions of 
Microsoft JScript(R) and Visual Basic(R) Scripting Edition (VBScript). 
Documentation for the new features in Windows Script 5.5 can 
be found on the Web at: 
http://msdn.microsoft.com/scripting/

You can read about the most important new features in JScript and 
VBScript at the following Web site:
http://msdn.microsoft.com/workshop/languages/clinic/scripting121399.asp

The updated Windows Script engines will also be posted for 
individual download from http://msdn.microsoft.com/scripting/ 
so they can be installed on computers that are not running 
Internet Explorer 5.5 - for example, on an ASP Web server.


The Microsoft Office Developer Workflow Toolbar
-----------------------------------------------
In this release of Internet Explorer, the Microsoft Office
Developer Workflow Toolbar control will not data bind properly 
on a Microsoft Access data page. This control was affected by a fix 
in Internet Explorer 5.5, so an update of this control will be 
necessary. For the latest updates, visit the following Web page:
http://microsoft.com/office/


Printing Controls
-----------------
The re-architecting of the print code in Internet Explorer 5.5 
Service Pack 1 has exposed print bugs in several third-party 
controls, causing some controls to print improperly and some 
not to print at all. Although we have strived to maintain print
compatibility, we cannot ensure that all third parties will have
corrected these problems.   


HTML Buttons with Unselectable Attribute
----------------------------------------
When the "unselectable" attribute in Internet Explorer 5.5 is applied 
to buttons, the default onclick action (depressing the button) doesn't 
take place. A simple workaround is to add a behavior to buttons that 
causes this action. Add the following to the top of the file containing 
the unselectable buttons (or to a CSS stylesheet that's referenced 
from the  file):

<STYLE> BUTTON  { behavior:url("***.htc") } </STYLE>
   (where *** is the name of the htc file that contains the behavior)

The htc file should contain the following:

<component>
  <attach event="onmousedown" onevent="element.style.border='thin inset'">
  <attach event="onmouseup" onevent="element.style.border='thin outset'">
</component>


=========================
APPLICATION COMPATIBILITY
=========================

Task Scheduler in Windows NT 4.0
--------------------------------
Windows NT 4.0 included an old version of the Schedule service, 
also known as At service (Atsvc.exe). Internet Explorer 5.5 
upgrades it to the new version of the Schedule service, named 
Task Scheduler (MSTask.exe) and converts At jobs to Scheduled 
Tasks.

With the old At service, all At jobs had to run in the same 
account as the service itself. The default account for the 
service was the Local System account, but it could be changed 
to another user account as needed. Some Windows NT 4.0 users 
changed the At service's account because they needed their jobs 
to run in a user account. 

With Task Scheduler, each scheduled task can be configured to 
run in a different account. The Task Scheduler service itself 
has to run in the Local System account.

For backward compatibility, Task Scheduler allows the user to 
set one account to use when running scheduled tasks that were 
created from At jobs. When Internet Explorer 5.5 is installed, 
this account is set to the Local System account. If you are 
running Windows NT 4.0 and you change the account that the At 
service ran in to something other than the Local System account, 
then after installing Internet Explorer 5.5 you need to manually 
re-enter the user name and password for that account. To do this, 
go to the Scheduled Tasks folder, click the Advanced menu, and then 
click AT Service Account. 

This must be done manually because Internet Explorer 5.5 Service
Pack 1 Setup cannot decrypt the password that was used by the 
At service.

For more information about At service compatibility, see online 
Help in Task Scheduler.


Selection in IFrames
--------------------
In Internet Explorer 5.0, if a user made a selection inside an iframe
