Hi,

1.     Has the game ever worked earlier or it is the first time you are trying to play?

2.     Which operating system is installed on the computer?

Method 1:

You may try the steps from the following link and check if it works:

Flight Simulator X: “An error occurred while attempting to activate the product The problem may be due to an incomplete installation of the application”

Method 2:

Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

    I changed the partmgr.fltsrv in PartMgr.fltsrv and suddenly I could activate Acceleration.

    It was great :-)

    Thank you, thank you, thank you!

    W ooOOOoOooOOoW

    That was amazing!!! I don't really know what i just did, but it was amazing that by only changing that I could activate the expansion pack!!

    In y case all i had to do was to change the "p" and the "m" to capital letters, the value was not "0", but "partmgr"...

    Thank you a lot!!

    I have been looking for months and this was exactly the problem.

    Changed it to PartMgr and worked right away!
