VS is Visual Studio. You will need to:

1. If you don’t have sln file project then Right click on your uproject and generate Visul Studio project files.
2. Open sln file.
3. In Visual Studio check for Programs directory.
4. Right click on UnrealLightmass project and select Rebuild

So what happens when there is no “Programs directory” in the sln file? I can’t rebuild in VS because my sln file is missing that directory that contains unreallightmass.cpp
