Thanks L. Rahyen and vitamin, I figured it had its own directx, but wasn't sure what to do. OK. I updated my wine to version 1.1.13, and removed the .wine directory. I also managed to get COD4 installed, but receive error r6002.I have a few questions now. 1. What is the wine prefix, and how would it be damaged? It came preinstalled in ubuntu. 2. After reading through some forums, it says that I am likely missing dlls and to try using winetricks. But I also remember reading that you shouldn't use winetricks because it modifies the default files, making it harder to diagnose a problem with wine. Also, if you use winetricks, not to submit a bug report. Should I use winetricks, or is there a better way to go about adding missing dlls? Between work and school, I don't really have any time to play games (I've been playing Treasure of the Rudras on the Wii Virtual Console for 6 months now and haven't beat it) I am just doing this to gain a little bit more knowledge on how to use linux. I am mainly doing this so friends of mine will be willing to try linux. So, should I avoid winetricks in order to help the maintainers of the software or is it ok to use it and still report a bug?
