Can't (or don't know how) to open my custom Build of the Engine

Guys, I’ve compiled a custom version of the engine (one gameworks tech), now I’m not sure what to do with the compiled engine. I can’t open it in anyway neither I can open any example project that comes with Gameworks I just gives me the error: Failed to launch editor
(I also tried to switch the project version to the custom build)
Any suggestions?

I just fixed the problem, I wasn’t building the right thing inside Visual Studio.
