FrameMaker 2015 won't launch

I have Windows 7, and have been using FrameMaker 2015 as part of the Technical Communication Suite. It is the only application in the suite that I have installed. Suddenly, it will no longer launch and give a message "Unexpectedly Quit".

I tried reinstally. No luck.

Then I tried uninstalling before reinstalling. No luck.

Then I tried uninstalling, reinstalling and restarting. Now the program starts okay.

But after I downloaded and installed the update for 2015, FrameMaker again stopped working.

After another uninstall/reinstall, it is working, but without the update.

Is there a fix for this so that I can run it with the update installed?
