Hm. Installed the GOTD version, and went to the GOTD "activate now" site, and it says "TwistedBrush Pro Studio 17 activated - what next?" (but no serial or anything). But TwistedBrush asks for serial+key which that page doesn't give me...
Oh, scratch the above - the URL the installer gives is wrong (even though it seems valid), you have to visit the link in the readme... seems to work. What happens with GOTD programs if you ever have to reinstall, btw? I assume the original installer doesn't want to run after the GOTD-day
(A plain copy of the files from my VM to my workstation seems to work just fine, so that's kinda solved... at least the technical part. What does The License say?)
