David, is your answer based on personal experience or on the Google search?
I've been in the IT business for 35yrs. Uninst/Reinst is NEVER the first course of action, but the LAST! I have been researching this for 4 days and can find NOTHING that relates this file FMPro11. I found the same searches you already suggested.
As such, your solution is one that I'm considering but it's not necessarily the best.
