UPDATE: Installed Wine1.3. Reinstalled dotnet20 and IE6. Reinstalled Alibre. And... Getting much further this time round :D Program starts up fine. The work area shows the proper gradiated background. Toolbars are still missing unfortunately but I tried to create a sketch using the drop-down menus. Just a basic square... it didn't show the sketch lines but the vertices were there. It let me dimension it to different sizes. When I tried to extrude the sketch to create a cube I got an error message and it failed to create the extrusion. Definite progress though.
