I first used FTM 2006 on a desktop PC running XP. Now use it on a laptop with Windows 7, 64-bit operating system. It all works fine though I think the online resources link and Contact other Researchers link don't work, not that I ever used them. I think I just installed the program using the disk supplied and then did copy & paste from a memory stick of the saved tree from the PC. When I've done lots of updating on my trees on the laptop, I copy & paste the updated tree back onto the XP PC as extra backup and it is all OK.
I have heard that the 2012 version is too fiddly and not as easy to use so hope I can carry on with the 2006 version. Wonder why yours won't work? Perhaps someone else can advise...
