Globally set D3DVERSION variable to DirectX 9

Set the DirectX9 compatibility variable as Windows environment variable(QV_D3DVERSION) for all users using this CMD file. CMD will ask for Administrator privileges(UAC) if not run as administrator. This will fix display artifacts for some of NVIDIA cards and driver versions.

To use:

1. Download CMD file

2. Run CMD as administrator or confirm UAC window when asked.

3. If no admin rights granted then the variable will not be set.
