I have done a new wineprefix as stated. Winetricks worked correctly, and I installed d3dx9_26 and msxml3. Civilisation still will not start, though. So I next tried installing: d3dx9 d3dx9_28 directx9 msxml4 Still, not working. The error message is the same as it ever was, about failing to initialise the renderer. I installed Civ4 on a different drive, not within the wine directory. So I did not reinstall it. Does this seem a necessary thing to do? I have no issues running Poser 7 and various other wine apps from additional drives. The appdb does not appear too helpful: http://appdb.winehq.org/objectManager.php?sClass=version&iId=16878 I await farther instruction. Any other ideas?
