i guess i was lucky then.. can you tell a bit more about the issue you had so others might be helped?
The common thread among the MANY errors I found people have reported seems to be caused by running out of disk space during the install. When this occurs the install halts and leaves both VS2005 and .NET 2.0 in an unusable state. Simple freeing up disk space and clicking retry does nothing. You can't remove .NET 2.0 or VS2005, and they don't work either. You are hosed.
In my case, I had 1.5 GB free before doing the install, and figured that was enough. The install started up normally, but died a ways in. In the end, it seems like you better have 3+ GB free before attempting this according to some posts I read. I cannot verify that though.
The fix in my case was to delete the C:\WINDOWS\WinSxS\Policies folder, then completely remove .NET 2.0 and VS2005, then reinstall them.
I am not going near SP1 again until I know they have fixed the package. I have never had a more frustrating experience installing anything - and I am not new to .NET or VS.
