FreeCAD Black Screen workaround

Got a window filled with black when attempting to start freeCAD's portable app (v. 0.21.1).

Symptoms are described here:

As discussed in the FreeCAD forum, renaming FreeCAD's bin/opengl32sw.dll to opengl32.dll fixed the issue. The Path to the file is something like ...\PortableApps\FreeCADPortable\App\FreeCAD\bin

Hope that helps, thanks!

Lacking OpenGL Driver

This can happen with multiple apps if your system doesn't have a proper graphics chipset/driver, typically on laptops. You can add that same opengl32.dll file into apps like Blender (if I recall correctly) to get them to work as well. It's downloadable from Mesa3D.

Sometimes, the impossible can become possible, if you're awesome!
