My friend is new to FSX and he had installed it into his program files on his hard drive.  He recently bought a SSD and he said he copied it over to his SSD.  It worked a few times he stated but now everytime he tries to start FSX it comes up and says it is not installed and won't work.  Any feedback would be greatly appreciated.  I want to get him back up and flying again.  Thanks.

I would un-install it , then re-install on your C Drive. Copying it just doesn't get it.

I always thought once you bought software you cold install on your own computer as many times as you wish. Well not true with FSX! After installing a number of times it will not accept your product Key. You have to call a number to install and who knows how long this may take or even work. I guess I might as well buy a new FSX. After all it is much cheaper. Does this seem RIGHT?
