To use ColorMagic, you need to run CLRMAGIC.EXE in your ColorMagic application directory. Under Windows 3.1, you should create a Program Manager icon for CLRMAGIC.EXE. Under Windows 95, you should add a shortcut to CLRMAGIC.EXE to the Start menu, and/or place a shortcut on your desktop. In either case, consult the Windows documentation to find out how to do this. You can always run ColorMagic by double-clicking the CLRMAGIC.EXE file in File Manager or Explorer.
