- Quick search in MainType 5.0 build 617 to filter by font name
- Refresh the font folders
- Select the four installed fonts and uninstall them
- Invert the selection
- Install the four new versions (regular, italic, bold, bold italic)
- Invert selection
- Remove and ignore the old versions.
FontService.exe is running at 95% CPU, but nothing changes.
To recover the situation, I rebooted, and restored the ignored fonts, then installed the new fonts, and removed the unwanted fonts again.
It may be that I am too quick — trying to remove fonts before the installation of the new ones is complete.
