Visual Studio has bunch of extensions that it has released over period to support applications like SharePoint, InfoPath, Office etc.

When you try to open project that was built by using one of the template provided by this extensions you end up getting error:

Project type is not supported by this installation.

Here are the steps you can follow to over come this issue and finding the tool kit that is required by the project:

1. Open ProjectName.csproj in notepad
2. Find out node and get Guids and Google it, more than likely you will know exact kit that is required.

Happy Programming!
