I have this error with TripleX.cpp.

The tutorial I’m trying to follow is on the left. This is my screen on the right. I have no idea what “‘cl’ is not recognized as an internal or external command, operable program or batch file.” means. Hopefully someone here will.

It’s not the .cpp file that is causing you issues. It’s the cl command that is – probably something you need to set up in your %PATH%
