I have the same issue with Cave Story Plus. Steam downloads game files and installs the game. When starting the game an error window pops up which states that the executable is missing. Looking at the game's directory in the steam folder, I can't find an executable or script to start the game.
I am using Steam built on Jan 11, 2013 14:43:42, Steam API v012, Steam Package Version 1357953871
Nice, so why is available on the installation?
Nothing extracted yet.
does not install from Steam, and if havent gam on hdd then does not run: missing executable
