165646 Program Settings Lost After Internet Explorer Setup or Uninstall

When you install Internet Explorer 5.5 over Internet Explorer 5 or 5.01, its uninstall behavior varies depending on whether the Internet Explorer uninstall information (used to restore the version of Internet Explorer prior to 5 or 5.01) is present and whether the Internet Explorer 5.01 installation created minor version uninstall information for Internet Explorer 5.

If uninstall information is present when you install Internet Explorer 5.5, the uninstall process restores the computer to the version of Internet Explorer that is contained in the uninstall information (either the version installed before Internet Explorer 5 or 5.01 or Internet Explorer 5 or 5.01). However, if no Internet Explorer uninstall information is present when you install Internet Explorer 5.5 over Internet Explorer 5 or 5.01, the uninstall restores Internet Explorer 5 or 5.01 on the computer.

This chart lists the various upgrade scenarios and the Internet Explorer 5.5 uninstall behavior that can occur in each situation:                         Uninstall        Internet Explorer 5.5 Previous version     information      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      Present       Version installed before Internet Explorer 5 Internet Explorer 5     Not Present   Internet Explorer 5 Internet Explorer 5.01  Present       See note below Internet Explorer 5.01  Not Present   Internet Explorer 5.01 Windows 98 (Internet    N/A           Windows 98 (Internet Explorer 4.01 SP1)                    Explorer 4.01 SP1) Windows 98 SE (Internet N/A           Windows 98 Second Edition                                             (Internet Explorer 5)   Windows 2000 (Internet   N/A           Windows 2000 (Internet       Explorer 5.01                          Explorer 5.01) NOTE: In the case of uninstalling Internet Explorer 5.5 from an upgrade over Internet Explorer 5.01 where uninstall information existed, the computer is restored to the version of Internet Explorer contained in the uninstall information (either Internet Explorer 5 or the version installed before Internet Explorer 5).

For example, when you upgrade from Internet Explorer 4.01 directly to Internet Explorer 5, Internet Explorer 5 creates uninstall information to return the computer to Internet Explorer 4.01. If you then upgrade from Internet Explorer 5 to Internet Explorer 5.01, uninstall information already exists, so no new uninstall information is created. Finally, when you upgrade to Internet Explorer 5.5, if the uninstall information exists at this point, no new uninstall information is created. An uninstallation of Internet Explorer 5.5 in this case returns the computer to Internet Explorer 4.01. If you remove the uninstall information prior to upgrading to Internet Explorer 5.5, however, new uninstall information is created for 5.01. The uninstallation of Internet Explorer 5.5 in this case returns the computer to Internet Explorer 5.01.
