I have downloaded and installed the RC version of the VS2012 VS2012_RC_ULT_ENU.iso. Now, when I start Visual Studio, there's no project templates for C++ programs.
Here's this problem reported from someone else: http://connect.microsoft.com/VisualStudio/feedback/details/745797/no-c-projects-in-vs2012-rc-premium
Is this problem only for me or do I have to do something special?

You may also want to try with a different installation media.
