Hi, everyone. I'm wondering if someone has a clue about this error message because I've just upgraded from Vista to 7 and that error message seems to still exist. On my Vista I used to receive this error message during Windows Update of SP2. SP2 would never install because of the error. Now after upgrading to Windows 7, I've been doing my updates and discovered that the error has popped up on another update, this time the 'Microsoft .NET Framework 3.5 SP1 Update for Windows 7...' I have a theory about this error message. I've researched it thoroughly and what I've come up with is perhaps it has something to do with Microsoft no longer providing support for SP1 a small time ago. I came to this conclusion mainly due to any updates relating to SP1 and the like, but I could be wrong. My question is, does anyone have any other idea as to why this error would come up during Windows Updates? Note: I don't have any antivirus programs because I've just upgraded (custom installation) so the problem can't be that. Thank you!
