Is this permanantly added to my library now?

How do I fix when it says missing executable when I try to start the game. Thanks for any help. I have changed download locatins numerous times.

Getting a Failed to launch the game, missing executable message. Does this have to be installed onto the same HDD as Amnesia or only on the C: drive ?

Does anyone know the name of that music ? :)

im triyng execute the game, but the steam say ''cant launch this game have no exe''' I dont know a fluent english sorry
