Tried to install FSX on to my new build today and all went smooth  until activation time. An invalid error came up and I have tried everything in the book, I've called and they couldn't help, I unchecked the Compatibility box, and I've completely re-installed. I am at a loss of where to go here. Any help would be appreciated!

GWC123, Thats bad for you. First i wanna know: What is the message?

 

Here i got some examples what went wrong:

1. Your Activation Code is already used serveral times (you got 3 liceces) Most likely
2. Your code is not in the 'code database' of Microsoft
3. FSX is not correct installed Not likely

Oh, and Microsoft can't help you, Microsoft Game Studio's stoped in 2009 to make and support the games they make. So the help is too old.

 

Next time for any problems in WIndows, Programs errors got to here: http://answers.microsoft.com/

 

I hope you can make a picture of the error message
