Yes, I really do need the original program. I tried several opensoftware-progs but I stick to autosketch. It is exactly what I need: not too much possibilities, but not too few neither. And further on, I would have to convert all the files I have.
I searched for the compatibilty of (auto-)sketch with wine but didn't find it in the lists. In the past, I used to run autosketch with wine under ubuntu, that went just fine, but since I prefer Mint I wondered if f.i. LMDE is better with virtual machines then f.i. xfce or the "regular" Linuxmint with long-term support.
Another question is: which VM runs best with LMDE, with xfce or with Maya? (I have installed all 3 of them)
