Source SDK Base 2013 Multiplayer\hl2 doesn't have .dlls in the bin folder Source SDK Base 2013 Multiplayer\sourcetest does have .dlls in the bin folder, because your mapping for Gmod set H++to compile and save the bsp to the Gmod maps folder then launch map from gmod

inthe build programs tab change this line

it'll build and save the bsp to gmod maps folder you then launch the map from gmod

no just untick the run box like this

if you change the game exe it'll mess up the windows and you'll have black view ports

tools >options the build programs tab should look like this

you only change where the compiled bsp is put
