RE: NULL length .EXE still generated?

This is most likely a paths issue. QB64 creates a NULL length .EXE file (this is a workaround for deleting the old .EXE silently) before calling a second batch file to compile the actual .EXE file from the C++ code. For some reason the second batch file wasn't found/run.

Try running it manually by typing the following from the directory where compile.bat is found (you base QB64 directory)
.\internal\temp\contcomp.bat

Tell me what happens,
