--- Comment #5 from reg.cowell@gmail.com 2013-04-24 10:38:16 CDT --- I have found that the problem is associated with installing wine on a Dual Boot, Windows 7 HP 64 Bit/Linux Ubuntu 12.04 system. I built a new system on the same machine with just Ubuntu 12.04 64 Bit LTS, installed 'wine' and then installed ACT2000 and then AutoCAD97 and all works fine. Is this something to do with wine finding the Windows partition on the disc?
