Your partial first post on this subject:
"I'm running Windows 7, and received several Windows Updates this morning, including several to the .NET Framework, on which I understand FTM 2012 is based.
After the updates and reboots, FTM 2012 will no longer open. I've tried repairs to FTM 2012, from Control Panel/Programs, but still no go."
My further response/idea
Yesterday I indicated I had dowloaded the .NET updates and was experiencing no problems. Thought this might be because My System was XP and/or because I don't do Synchs
Today when I tried to open up FTM 2012 it said I had improperly closed the system and should compact my file
I told the system Ok, assuming it would load and I would just compact ----but it didnt load and I tried it a couple more time and it didn't load
SO I WENT DIRECTLY TO THE FOLDER WHERE MY FILE IS STORED AND RIGHT CLICKED ON IT AND ASKED IT TO OPEN USING FTM 2012 AND IT DID OPEN
SO MAYBE YOU SHOULD TRY THIS METHOD -JUST SKIP THE SHORTCUT YOU MIGHT HAVE AND GO DIRECTLY TO THE FILE AND OPEN IT FROM THERE ----MIGHT NOT WORK BUT DOESN'T COST ANYTHING TO TRY
PS WHATEVER THE PROBLEM WAS IT HAS GONE AWAY AND I AM ABLE TO OPEN THE FILE DIRECTLY BY USING MY SHORTCUT ICON
