FSX Activation

I have the same problem, can install the Deluxe Edition but get an error when I try to activate. I found that are two updates to FSX, SP1 and SP2. SP1 does not fix the activation problem and SP2 will not allow me to even start FSX without an error. Backed
out SP2 in order to start FSX.

Hi Mark_582! My name is Ricardo an independent advisor ready to help you with this situation!

Unfortunately there's no official method currently to activate it, as you mentioned is no longer supported

Okay, I started the game again and was able to activate it using the product key. The game worked great.

Then I installed FSX Acceleration and, when the activation screen popped up, there was a small box that asked me to enter the activation key, but no place to type it in. I was able to start FSX again, but not activate the acceleration software.

Now what?

Thank you again. I will try. Can you help me activate Fsx Acceleration?

Hello, Rudy SALTZMANN

Welcome to Microsoft Community.

The FSX Gold Edition is the newer version as it includes the Deluxe Edition and the Acceleration expansion pack.

The activation process can sometimes be tricky, especially on newer operating systems like Windows 11. First, run FSX in compatibility mode for an earlier version of Windows, such as Windows Vista or Windows 7. If you encounter issues with the Acceleration disk not prompting for a key, you may need to edit the registry or use the FSX Software Licensing System Reset Tool. Ensure that FSX is properly installed and activated before attempting to activate the Acceleration pack. Detailed steps can be found here:

If you are still encountering difficulties, it may be worth considering upgrading to a more recent flight simulator platform such as Microsoft Flight Simulator 2020 or X-Plane 12. These platforms have been developed with modern systems in mind and provide a remarkable level of realism and expansive environments.
