I'm not a current Archicad user but was in the distant past....
I've got some files dating from 1999/2000 - Archicad version 6.
They are too old to open in the current demo version of Archicad.
I've found that you can download old (versions 9 and 10) of Archicad for file conversion purposes.
The files are too old even for Archicad 10 to open.
It looks like Archicad 9 could open them...but I'd need a mac with Snow Leopard to run that, and I don't have one.
I've fiddled around a bit trying to get Snow Leopard working on a virtual machine on my current mac(s) but no joy.
Do I have any other options....?
Any help appreciated! Thank you.
