Ahh I see! Did you know you can install DX 9c on 7 despite 11 being present? You won't be able to on the next version however as the "incompatible with this version of Windows" message will appear there.
For many older game titles the latest and more recent driver sets and Catalyst versions have been a problem. There was quite a discussion on this in the stick on the Latest AMD/ATI drivers some time back when from the Cat. 10 5 on saw many asking questions. Latest AMD Catalyst Video Driver for Windows 7
I'm running an MSI Radeon 5750 1gb card here still seeing the old Catalyst 10. 4 version which was still newer then what came on the software disk but allows for some real old DX 7 Legacy to XP compatible titles to run. After that one the discussion went into the hard coding problems for OpenGL and a few other things as I recall.
Once you changed the game setting for DX 9 all went well showing you may be bettter going for the 9c redistributable package to see 9 installed there and may want to see if your card will run with the Cat. 4 by chance. I still haven't had a chance to see if AMD ever got that situation corrected as far as the old coding issues to run a newer version of the CCC.
Remember this version of the CCC is about 2yrs. or older at this time about when the two models we each have were first seen. The AMD support still has it available for both 32bit and 64bit alike. The 64bit flavor is found at ATI Catalyst
Some sites still have the full DX 9c onhand for download since your game problems are likely due to them looking for 9 not 11. The download link is found at the bottom of the left column on the page seen at Download DirectX 9.0c (full package) Windows Drivers - Software Patch.
The game titles you named are actually quite a bit newer where you may not run into any problems with the present or recent catalyst versions. The option for the 10.4 CCC is for any released back in 2005 or earlier that run into OpenGL problems or simply won't install or run.
For any that came out between 2005 and 7's 2009 launch most were still looking for DX 9 where the full package is a good idea if you didn't already see the older DX version put on previously. I guess the 64bit 7 will be the last Windows version that will see some oldies still run!
