I get this on my command window after opening Rhino 8.
Shouldn’t the font come with the Rhino installation?
On my Windows R8 this is installed as SLF-RHN Architect.ttf in the folder Program Files%\Rhino 8\System\
The file is also present in the R7 System folder.
Hmm I deleted a R7 folder. I also had Rhino 8 open and tried to delete a Rhino 6 folder and it said it was in use…
I will uninstall everything and install Rhino 8 alone and check again.
Okay after uninstalling and reinstalling the problem seems fixed now.
But I have a new one: There are no templates 
Uninstalling and reinstalling typically doesn’t solve all that much.
I’d try a “Repair” from the Windows Control Panel.
