.NET 4 and error 641
I forgot to blog last night. I was in the middle of trying to get two LOVELY .net 4 updates to install that I forgot to tell you how I finally got them working.
At home I installed Windows 7 sp1 and it got stuck in rebooting. It rolled back, I did it again and I thought it went on okay but obviously it didn't as it manifested a problem with the Windows installer service. I kept getting a "641" error. Finally traced it back to this not failed/but failed Win 7 sp1. I ended up doing a sfc /scannow command and that's what fixed the install and let the .net 4 patches to install.
Now I'm stuck on the last one
Filed under: Patching issues
Installation Failure: Windows failed to install the following update with error 0x8000ffff: Security Update for Windows (KB2567680).
Wish me luck.
