You cannot perform a repair installation of Windows XP if Internet Explorer 7 is installed. If you do, Internet Explorer will not work because the repair installation does not restore the earlier version files in the %ProgramFiles%\Internet Explorer folder resulting in an incompatibility with the Internet Explorer 6 files that the repair placed in the %SystemRoot%\System32 folder.
To uninstall Internet Explorer 7:
1. Start / Run / appwiz.cpl / OK.
2. Select Internet Explorer 7 and press Remove. If you can't find Internet Explorer 7:
B. Restart you computer and start the Recovery Console.
C. Type CD ie7\spuninst and press Enter.
D. Type batch spuninst.txt and press Enter.
If SP2 is NOT installed and Internet Explorer 7 cannot be uninstalled:
1. Delete the %SystemRoot%\IE7 folder if it exists.
3. Make sure the Internet Explorer 6 is working.
