Error installing the .NET Framework 2.0 SP2 Security update KB974417

First of all, check the WindowsUpdate.log file found in the Windows folder. It should tell you how the update failed. Look for something looking like this: WARNING: Command line install completed. Return code = 0x0000066a, Result = Failed and later on WARNING: Install failed, error = 0x80070643 / 0x0000066A.

If you have the same error, check this article out: Fix KB974417 Installation Failure—Microsoft .NET Framework 2.0 Service Pack 2 Security Update for Windows 2000, Windows Server 2003, and Windows XP.

However, my problem was that I had NOT installed the KB976569 Windows update that the guy recommends removing before installing the new one.

I found this article: KB 953297 and KB974417 Fails to Update Through Windows Update that recommends a clean reinstall of the .NET Framework. Haven't tried it, though. I just didn't do the update. Probably when all hell breaks loose I am going to regret it, but at least I passed the message on :)
