I puchased FSX new on Amazon last week.
It arrived, I installed it and downloaded the SP1 and SP2.
Now, I try to activate it and tells me the product key is invalid.
I have tried for hours to get support from microsoft with no luck.
Anyone else had this problem?
What can I do?
Try deleting SP1 and SP2 and see if it can be activated.
If not, keep calling the activation center.
Had same problem before SP1 and Sp2 were installed 😞
Then to only thing you can do is call.
Odd, I've moved it to 3 or 4 computers over the years and never had a problem, too bad.
