I get the same error:
Could not parse Engine Version from ObjectVersion.cpp: Could not find a part of the path ‘C:\Program Files\Unreal Engine\4.0\Engine\Source\Runtime\Core\Private
UObject\ObjectVersion.cpp’.
ERROR: Couldn’t find module rules file for module ‘MCPP’.
The command line is pulled from the editor Output log (see attached)
As for the directory, it is where I installed the binary package, although I do have the sources elsewhere.
