ASP.NET MVC project "not supported by this installation"

I can create new MVC projects and they work and run however trying to open an existing project is not working at all.

I tried the following changing the project type to:

<ProjectTypeGuids>{F85E285D-A4E0-4152-9332-AB1D724D3325};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>

(this worked on migrating a project from Asp.Net MVC preview 1 to preview 2 BTW)

Changed the Reference to:

<Reference Include="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
    <SpecificVersion>False</SpecificVersion>      
</Reference>

I tool this from a new project I created so i know that should be OK (I even hardcoded the path to the same result).

Still I get the dreaded:

The project file '.....csproj' cannot be opened. The project type is not supported by this installation.

I also tried devenv /setup and installing the SP1 for Visual Studio.

The project I'm trying to open is this one (a DevExpress sample of a grid working on ASP.NET MVC).

ok the problem was too many changes, I unzipped the solution again and just changed the first parameter in the ProjectTypeGuids to {F85E285D-A4E0-4152-9332-AB1D724D3325} so it looks like

<ProjectTypeGuids>{F85E285D-A4E0-4152-9332-AB1D724D3325};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>

and I can see the project hurray!

You need to install ASP.NET MVC 2.

There is a really easy way to solve this.

Probably some of the dependencies are missing, and it is really hard to find out which one.

Go to

http://www.asp.net/downloads

Download ASP.NET and WebTools for your version of Visual Studio

A web platform installer will come up, which will install all the required tools

This solved my problem

There is no need to go through the ProjectTypeGuids

Just had a similar problem when taking an older MVC / Azure WebRole project into VS 2012 with MVC4. The trick was to edit the .CSPROJ like this:

10c11
<     <ProjectTypeGuids>{F85E285D-A4E0-4152-9332-AB1D724D3325};{349c5851-65df-11
da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
---
>     <ProjectTypeGuids>{E3E379DF-F4C6-4180-9B81-6769533ABE47};{349c5851-65df-11
da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>

i.e. change the first one from {F8... to {E3E3... (which is apparently MVC4). This has to be done outside of Visual Studio, in a text editor, and then open the solution and "Reload" the project that gave an error - this will trigger VS to migrate it to VS 2012.
