After update, I don't see any Winforms menu under the Telerik menu. Also, I'm unable to add new Winforms to my project. The only thing I can think of that caused this upgrade to be different than all the others is me uninstalling VS 2012 prior to upgrading VS 2010.
How do I re-establish my VS 2010 environment?
