Answer 1

In Windows 7 if you are not running as the local "Administrator" and have UAC turned on the install will silently fail. The solution is to disable UAC, reboot, and the install should succeed.

Answer 2

VS2008; ASP.NET MVC 2 on 64-bit machine receiving the issue:
"the project type is not supported by this installation"

Solution: Thanks to Bert Huijben from above. Under the VS install in the start menu, in the VS Tool folder, ran VS2008 x64 Cmd Prompt. Executed commands:

devenv /setup

...still project errored and didn't open, then ran

devenv.exe /resetskippkgs

... and then success!

If you are running Visual Studio 2010 and want to open/create MVC 3 solutions you have to have the Visual Web Developer component of Visual Studio installed.

If you have done a default installation without customization then this component is installed.

If you do a customized installation and say thought you only wanted C# stuff installed you may have unchecked the Visual Web Developer component thinking you didn't need it. You need it for any MVC development. Simply re-run your VS setup and make sure this component is selected.

The MVC 3 download and installation will work properly even without this component installed. However, you will not be able to open or create a MVC 3 solution.

Answer 4

The problem is that MVC 2 is not completely backward compatible. Visual Studio cannot open MVC 1 apps without MVC 1 installed. So if you just install MVC 1, which can install together with MVC 2 you should be just fine. http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=53289097-73ce-43bf-b6a6-35e00103cb4b

Answer 5

Ran into this problem when I had VS2008 running by accident when I started the ASP.NET MVC install. Closed VS, uninstalled ASP.NET MVC, then reinstalled it and everything worked fine.

I tried some of the solutions posted here but still no joy. Finally I replaced the ProjectTypeGuids to this one below in the project file and it loaded fine

<ProjectTypeGuids>{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
