Switching from free to checked/debug compile[edit | edit source]
To switch to the checked/debug compile, you will need to install the SDK. Launch setup, and on the page where you select the components, select only "Debug binaries". After installation, select "Debug Windows 3.1" or "Debug Enhanced Windows 3.1" in the "Windows SDK" program manager group. After a restart, Windows will start, but a watermark appears at the bottom right of the screen saying "Debug Windows 3.1". This means that now the checked/debug compile of this build is running.
To switch back to the free compile, select "Non-Debug Windows 3.1" from the "Windows SDK" program manager group. After another restart, you are back.
