My old X6 version had an option which automatically installed missing fonts from the Bitstream font catalog when opening a file with missing fonts. Has this option been removed in the 2019 version?
It's now called Corel Font Manager, did you install it when you installed Corel 2019?
Yes, have it installed as well, however the function is missing
Open the program and add you font folders so it knows where to look for your fonts
That's actually one of the first things I did.
Try resetting the Font Database, Hold down the F8 Key as you restart the Font Manager and Agree to resetting the program.
A properly functioning and default configured Corel Font Manager will allow the use of any font installed in the font database. Even if the font is not installed in Windows.
