Can someone on Windows explain the right thing to do here?
Unfortunately, I'm not on Windows. Probably, lyx.exe is not in your path, but I don't know for sure. Someone else will.C:\Users\MyName>lyx.exe -help 'lyx.exe' is not recognized as an internal or external command, operable program or batch file. ... and I'm stuck. Are there any simple resources on how to get started with the very basics?
