Hi,
I'm running Windows Server 2008 R2 and Visual Studio 2010 SP1 and I'm trying to install ASP.NET MVC 4 using the standalone installer.
The installer fails instantly with error "0x80070648 - Unknown property". The logs indicating a problem with NuGet:
[20B4:18A0][2012-11-13T17:38:54]: Registry key not found. Key = 'Software\Microsoft\DevDiv\vns\Servicing\10.0\xcor'

I found NugetVS2010.msi on my drive and run it but it didn't change anything. I've also tried uninstalling and re-installing NuGet.
Any suggestions?
