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)

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.

Thank you, this allowed me to finally migrate my 2010 solution to 2012 which happened to on a different machine than it was originally created on. 2 years of looking finally resolved my issue. – Michael Jan 4 '17 at 1:58

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!

+1 -- too many other related posts. This one worked in VS 2008 for me with MVC2. – Kurt Johnson May 24 '10 at 17:26
Do you know what 349c5851-65df-11da-9384-00065b846f21 (the second one) represents? I've worked out that that's the one I'm missing from my machine, but I have no idea what it is an what I should install to get this... – Flater May 24 '12 at 13:48

This worked for me as well with VS 2008. Thanks. – ghost_mv May 15 '13 at 19:54
