RoboHelp 11 Crashes on startup

I was previously using RoboHelp 8 on Windows 7 64-bit. Yesterday, I uninstalled RoboHelp 8, and installed Technical Communication Suite 5, selecting RoboHelp 11, Acrobat, and Captivate. Now, When I try to launch RoboHelp 11 from the Start menu, the app crashes immediately. The crash details are as follows:

Is there an easy way to fix this? I have tried running it as Administrator and not as Administrator, and it made no difference.
