I have a standalone installation of Stock Car Extreme.
When I select the game in the list of Crew Chief I make sure to edit the path of the game. In my case is D:\Games\GSC2013\GSC.exe

But then I start Crew Chief and it says it needs to install files for it to work. I'm okay with that, so I click Accept. But then I start the game and Crew Chief doesn't work.

Then I stop Crew Chief and start it again and it tells me again it needs to install the required files!

What's wrong? Am I doing something wrong? Do I must do something more apart from defining the path of the game?.
