My company purchased these odd fonts years ago. I added them to the font file way back when, with no problems. I've used these fonts religiously. So they are literally in hundreds of files. Fast forward to the SW20 update at which time I had to get a new computer because of the windows thing. To date I have tried dragging and dropping, installing and C&P these fonts into the font folder. They seem to go in with no problem. However, when I open a 2D drawing or a 3D file with either of the fonts I get the SW can not find the  xxxxx font do want to look for it or use a temporary font message. Any suggestions?
