Steam Client keeps prompting me to install file that doesn't exist
I'm getting a UAC prompt every frickin time I run a game (any game) that Steam wants to run a file called "C:\Program Files (x86)\Steam\steamapps\common\Steamworkd Shared\runasadmin.vdf". From what I can tell, that file doesn't even exist. Doesn't matter if I say "Yes" or "No", it keeps prompting me.

Anybody else seeing this? It's really driving me up a wall.
