If you installed FMGS several releases ago a different font may have been distributed with the package. Current FMGS installers are unable to remove this font because of Windows restrictions. To reinstate Christoph’s default FMGS font you will need to manually remove the fonts in the \Windows\Fonts directory, and reinstall the latest FMGS.
There is a noticeable difference in the fonts. The Christoph fonts are distributed in the Jeehell FMGS freeware installer and should be the only version installed.

And the name of the font(s) we should delete before re-installing?
Look for the font names with ‘Screens’ and ‘MCDU’ and delete them. After you reinstall FMGS Christoph fonts should be installed.
