Validation error on FSX

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello Jeando, Ha corrupted installation is one of the possible reasons why you are unable to run the FSX Acceleration pack. To help you resolve this concern, we recommend that you perform the steps below:

Using System File Checker in Windows

CHKDSK

https://docs.microsoft.com/en-us/windows-server...

1 - Type cmd (Command Prompt) in the search bar of the Start menu and then click Run as administrator.

2 - Enter chkdsk /f/x/r/v

The system will ask you if you want to run CHKDSK after restarting the system, press Y on your keyboard and then type "Exit" and restart the computer, it will scan in DOS mode.

Games for windows live is all but unsupported at this point in time, It’s likely the source of your validation issues.

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.

Thanks for the reply. The things you have suggested, and many others, I had already done. While the validation form then appeared and appeared to work, it didn't. I have spent many hours trying to get this to work. As I said, my copy is completely kosher, bought for cash from an impeccable supplier quite a few years ago.

I have, however, managed to solve the problem and everything is now working just fine. I found and downloaded what might be called a 'hack; and it fixed it very easily. I might normally be reluctant to mention this, but when I have to resort to using a 'fix' that some spotty faced adolescent knocked up in his bedroom because one of the mightiest corporations on Earth can't be bothered to sort it out, I feel it's entirely justified.

I'm glad you were able to find a solution.

If you wanted to play the new Flight Simulator, I invite you to try PC Game Pass | Xbox where you have access to hundreds of different games, all our first party titles and iconic Bethesda games, new day one titles, and the EA Play on PC catalog.

With Game Pass Ultimate, you can also play from the Cloud, so you don't have to install the game on your device if you don't meet standard requirements for the game, and you don't have to wait for the install to finish to play.
