ISM software is primarily designed for the Windows operating system. Most versions and user guides are created for Windows XP, 7, 8, 10, and 11. It is available in both 32-bit and 64-bit versions. While it may be possible to use the fonts on other operating systems, the full typing software functions best on Windows.

If the font does not show up, try restarting your PC.
