Cannot Run Compiler 'cl'
I am having the same problem as: https://forum.qt.io/topic/81290/cannot-run-compiler-cl however; I don't have the same solution. I have all the compilers MS ever made and every version of Qt installed. No matter what I do, Qt Creator can't find cl.exe. If I do it manually in the command window, it works fine.
@drhalftone It sounds like you don't have your kit set up properly. That is where you point it at the compiler you want to use. Check that in settings and make sure you have a kit and there are no red exclamations.
