Whilst trying to install Visual Studio 2005 Service Pack 1 for Vista I received the following message:
"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..."
What I didn't realise was that I must install Visual Studio 2005 SP1 first!
