After uninstalling VS 2010 and reinstalling, and then subsequent reinstallation of MVC4, I am unable to open MVC 4 based projects. I get the typical "The project type is not supported by this installation" error.
Edit: My current ProjectTypeGuids
value is as follows:
<ProjectTypeGuids>{E3E379DF-F4C6-4180-9B81-6769533ABE47};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
Replace or remove the the ProjectTypeGuids to this one below in the project file if you are sure that installation is correct.
{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}
ref: "the project type is not supported by this installation" error
MVC project on VS2010 error : The project type is not supported by this installation
Please check Help Menu >> About Microsoft Visual Studio >> Installed products? Please check whether "Microsoft Visual Web Developer 2010" has been installed properly.
Hope these help..
