I can't find the exact solution to this matter but there is a solution to this with a little side effect.
First, go to c:\windows\system32 and find a file named gameux.dll. Change the ownership of the file to your username and tick the allow full control next to your username. Then just move it to somewhere else or change the file extension. I have tried it and it works.
