hello,

 

I already purchased PMDG 777 model and it worked very good no problems at all.

A week ago i had to update my pc to windows 8.1.

If i want to fly in fsx, i have to insert al product keys again, because i purchased them online, i dont have them anymore...

what can i do?

 

please advice

thx a lot

My guess is the the product key for FSX will be in your email somewhere or within your Microsoft store account if you bought it online.

 

Cheers

If you're referring to your PMDG product keys you can get them by logging into your store account at our website and choosing "View previous orders".
