My Elite Dangerous games folder appears to be found within the "Users Directory" on my HDD, using Windows 7 64 bit operating system. This might be the problem why my GeForce Experience cannot find this game as on the GeForce website is says
"GeForce Experience uses the locations specified in the Preferences —> Games tab to find games. Add the location where your game is installed if you have selected a directory other than the default game path.
The GeForce Experience Scan for games feature can only support unsecured directories. Directories that have access limitations (such as network shares, user directories, etc.) are not supported. "
I am going to reinstall ED to a different directory and see if this solves it for me.
