From the filename I guess it is Windows. Should work with:

�� LibC system: 'D:/DEV_FreeCAD/build/bin/box.step'

but note that .step is not a regular executable extension like EXE and other.
More a file type that is associated with the executable of free cad.

You can also check the Process class in https://github.com/astares/Pharo-OS-Windows
if you need more control.

For detailed questions you can meet me on Pharo Discord.
