QBPE 3.6.0 compiler error

[Kernelpanic]

Kernelpanic suggested adding something like "D:\Programs\mingw64\bin" . . .

You misunderstood something there. Add this path to the compiler to the Windows path, as shown in the screenshot.

however, QB64PE does not contain a \mingw64\ folder with a \bin\ directory.

Yes, the supplied compiler is here: "Programs\qb64*\internal\c\c_compiler\bin"

But that doesn't matter now. There won't work anymore, only a "tabula rasa" will help. Completely delete the whole installation of QB64pe! Then clean new start, new luck.

Copy the whole unzipped QB64pe folder to D:\Programs. Now right-click qb64pe.exe and drag it to the desktop, in the selection click: "Create shortcut here." Now it's on the desktop.
Now start the IDE and under RUN select "Output EXE in source folder". Complete. - Now it has to work!
