I never ever under any circumstance run a game as administrator. I installed the game as an ordinary user, so all directories involved are accessible with those permissions.
Trust me, if a game won't run but with Admin privileges, then you don't want to play it. The dev himself should fix the game to not require such prequisitions.
Besides, I searched the game's directories for that file, and found that it doesn't exist at all in my install, so I doubt that running it as Admin would fix it in my case. May I ask which download link you used? The file may be missing from the GoFile version only.
