AC29 Default font issues

Otavio A — Fri, 23 Jan 2026 12:53:53 GMT

Hello, I’m starting the process of recreating our office template in Archicad 29 (we were using version 27). However, when I started editing the properties, I noticed that the Property Editor is using a font that I don’t even have installed on my computer anymore, and it’s unreadable font at this size. Is this a bug? Is there a way to fix it?

Can you reproduce the error on a different machine? If not, then may I suggest you uninstall and re-install AC on your computer.

I'm no longer. much of a Windows user, but it might be corrupted registy entry. ???

That's an old bug that GS has never bothered to fix. No clue why it is so difficult, but if I remember correctly is was deemed an "impossible task" 😄

Only option is to find that font and uninstall it (and hope a better one is picked).

I couldnt reproduce the error on another machine, but i tried your suggestion and it didnt work...
i even tried to change the fonts in the regedit in windows and could change every single font in the program, except for the one in the expression edditor :c

It was installed again automatically? That's weird. Never seen this. Do you have a guess which software you have installed that does this?

The only option now I can think of is to delete the file again, but before you copy the file name. Then you make a soft link to a "good" font, like Arial, and rename the link.

Or, as you have tried, using the Registry. I think it supports Font Substitution, which should work everywhere.
