Can't install ASP.NET MVC3 RTM?

Question

I'm trying to upgrade from ASP.NET MVC3 RC to RTM? I can't get past upgrading the vs10-kb2483190-x86.exe installer. I get this error in the error log: Do I need to uninstall the Windows Phone SDK first? Should I hunt for GUIDs in the registry?

Answer 1

The installer appears to launch devenv.exe behind the scenes. I decided to launch VS2010 to see if it would "unlock" something. After it launched, I closed it and the installer started progressing.

Actually, it did work - I just ran for the second time...

When you run .msp, it pops a prompt that "the network resource for Visual Studio installation files is not available". Once you update the location of vs_setup.msi everything else works fine. I didn't have to run MSIs in sequence as the post suggests - once location was correct, I just ran MVC3 installation executable, and everything got installed fine.

It looks like platform installer and MVC3 setup just fail and, worse, swallow the root cause problem.
