--- Comment #2 from Rovanion Luckey rovanion.luckey@gmail.com 2013-02-03 07:28:57 CST --- winetricks dotnet20 told me to download the fallowing:
Please download dotnetfx.exe from http://download.cnet.com/Microsoft-NET-Framework-Redistributable-Package-x86..., place it in /home/rovanion/.cache/winetricks/dotnet20, then re-run this script.
Which I did. The problem being that I'm on a x86-64 installation so the installer naturally failed. I did try with this 64-bit package of .net 2.0 but it failed too for unspecified reasons: http://download.cnet.com/Microsoft-NET-Framework-Version-2-0-Redistributable...
So next I tried 'winetricks dotnet40' which did install. The game still won't start but gives another error, see attachment.
