I'm now working on RC windows7 and installed visualstudio2008-Professional edition. But I need to work with Java programs and so I needed to work with visualstudio2005. I installed visual studio 2005 -sp1 (vs80sp1-KB926747) but I have the following problem:
"The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch."
I previously had the same problem when I installed the VsSDKFebruary2007.
