Just around the time I decided to try the New Visual Studio 2010.
All of the sudden I started getting an Error.
"An Unexpected Error Occured
Could Not Load Type".
See screen shot Here http://pcsxcetra.com/VS2008DataError.aspx
I tried to uninstall and reinstal VS 2005,2008,VS 2010(didn't reinstall) and SQL Server also. Updated VS 2008 to sp.1 . Still no luck. Used a reg Scanner Program to find everything to do with VS 2010 and cleaned all Info I could find.Still didn't work.
Already had Windows SDK 7.1 installed. Thru Programs And Features(add remove programs)I did a reapir/reinstall of the Windows 7.1 sdk rebooted , got some odd error about C++ runtime then Did a Large windows update , rebooted.
Then went to start > Microsoft Windows SDK v7.1 > Visual Studio Registration ,
Then ran the Windows SDK Configuration Tool.Selected the latest version.
After that it started working again.
Almost forogt, I'm Running Vista 64 bit with UAC Disabled.
Somone else may want to start at the repair process first.
Hope this helps Someone
