IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs.

SYMPTOMS

After you run Microsoft Windows 98 Setup, you are unable to uninstall Internet Explorer version 5.


CAUSE

This issue can occur if you run Windows 98 Setup on a computer that is already running Internet Explorer version 5. Windows 98 Setup removes the ability to uninstall Internet Explorer version 5 to protect important system files.


RESOLUTION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).


To resolve this issue, uninstall Internet Explorer version 5 before you run Windows 98 Setup.

To work around this issue, use the following steps:

NOTE: The following procedure requires reinstalling Windows 98.

  1. Rename the Iemigrat.dll file in the Windows\System folder to Iemigrat.old. To rename a file, right-click the file, click Rename, type the new file name, and then press ENTER.


  2. Back up, and then delete the "IE System Migration" value from the following registry key:

    
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\ 
   Migration\100


  3. Reinstall Windows 98.



STATUS

This behavior is by design.


MORE INFORMATION

When you install Internet Explorer version 5 on a Microsoft Windows 98/95-based computer, it installs a migration dynamic link library (.dll) file, and backs up any operating system files it replaces. The migration file is installed because Internet Explorer Setup does not track the version of the operating system files it backs up. One of the functions of the migration file is to protect the files needed by Internet Explorer version 5 if you reinstall your operating system.
