I’ve created a font set using FC evaluation version in Windows 10. When I export to ttf/otf file it appears in the font folder containing FCP font files as ttf but when I try to install or copy to main font store I’m getting this error message "the file [name].ttf does not appear to be a valid font " . Any ideas? I thought evaluation version had all functions except was watermarked…
Can you preview the font in the Font Test window within FontCreator?
If so, you can preview the temporary font created with other applications while the font test window remains open.
As far as I know, you should be able to export a valid, but watermarked, font. If you can attach the Font Project *.fcp file to the forum, we can take a look at it
It seems the auto hinter causes problems with the font. Most likely because it is a symbol font. Since auto hinting is not suitable for symbol fonts, do disable it in the Font Export Settings dialog. Let us know your results.
