Build Error when running batch file., Also VS 13 express not detected.

hey,

i was trying to compile the source code but i get a build error:

UE 4 error.png

its driving me crazy, i cant compile anything.
additionally, Visual Studio 2013 Express for Windows isnt detected by UE4 when im trying to add new code through engine (which works cause i still have version 4.0 installed and runs perfectly).

please help, thanks :slight_smile:
