I downloaded a demo project that required ASP MVC4, and I used the Web Platform Installer to add MVC4 to Visual Studio 2010. All seemed well.
Then I used Nuget to upgrade the dependencies, along the way seeing that Nuget itself had a newer version which I installed.
And now I have the sequence of problems below:
When loading the project, VS presents what appears to be a helpful dialog below
The Web Platform Installer looks similarly poised to do something useful.
Uh-oh, the install craps out saying NuGet is somehow to blame and presenting a link that leaves me at an ASP Home Page of sorts but doesn't address the problem in any obvious way.
The Question!
How can I get my installation cleaned up and working properly?
