How to Reinstall Internet Explorer 6

If you're having serious problems with IE, one way to repair it is to run the Windows XP installation CD to repair Windows. But what if you don't have your copy of the installation CD on hand? There's another way: you can just reinstall IE 6, but first you need to edit the Registry so Windows will think IE isn't installed. Here's how: Open your favorite Registry Editor. Navigate to the following registry key: HKEY LOCAL MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{89820200-ECBD-11cf-8B85-00AA005B4383} Right click the value labeled IsInstalled and select Modify. Change the data value setting from 1 to 0. Close the Registry Editor. Now you can download and install IE 6 (with service pack 1) from the following link: http://www.microsoft.com/windows/ie/downloads/critical/ie6sp1/default.mspx Note that this also includes the installation files for Outlook Express. Also note that you may need to reapply Windows XP Service Pack 2 to regain the SP2 changes to IE (such as the popup blocker).
