I'd like to suggest that the default installation path on Windows be
c:\Program Files\Slickedit\Pro22.0.0\
rather than
c:\Program Files\Slickedit Pro22.0.0\
I don't like having my Program Files folder cluttered with multiple slickedit installations.
Also, why is it recommended to "add to path"? I never do it and as far as I can tell it doesn't cause me any problems.
