--- Comment #12 from Louis Lenders xerox_xerox2000@yahoo.co.uk 2008-06-08 07:32:56 --- Hi, with the following workaround i got at least the trial starting:
1. Start with clean ~/.wine
2. Do 'wget http://kegel.com/wine/winetricks && sh winetricks msxml3 dotnet20'
(Though Autocad2006 claims it needs .net 1.1, you get a crash updating a hotfix in the installer; so don't install .net 1.1, but do .net 2.0, that is enough to make the installer happy)
3. Start the installer, and choos custom install, and deselect "VBA" otherwise the installer will crash later on.
Could you try if this works for you too? Then we could add downloadlink for the trial
