I’ve downloaded the .zip of this project here:
https://github.com/SteveDunn/Gleed2D
And I installed Visual Studio 2010 Ultimate Trial and installed XNA 4.0. But when I try to open the included Gleed2D_Tool.sln file I get the error message:

I’m stumped by the incredibly useless error message. Does anyone know what I need to do to get this to compile?
The project types in the project files you listed are C# and XNA
Likely, as Mataniko suggested, you have either missed the C# installation as part of visual studio or XNA isn’t properly installed.
There is a list of project type GUIDs at http://onlinecoder.blogspot.ca/2009/09/visual-studio-projects-project-type.html. Of course the list may not be complete because anybody can extend visual studio with a new project type with a fresh GUID.
