When installing Visaul Studio 2005 on Windows Vista Build 5308 (Feb CTP) it was failing with the error that the minium requirement had not been met and i needed to install SP2 (silly setup)

I did two things to get past this so i am not certain which actually fixed the issue

  1. I went to the Windows update site and installed the Windows update utility -but obviousely didn't apply any updates
  2. I kicked off setup from the \setup\setup.exe not the setup in the root of the Visual Studio root directory....
