Yeah, you place both .dll's in your Cross Fire folder. It's located in C:\Program Files\Z8Games\Crossfire
Extract both .dlls on your desktop, highlight both of them, right click and select copy. Then go to your crossfire directory. Which like I said above is in C:\Program Files\Z8Games\Crossfire. Then right click and paste both .dll's there. Then in your crossfire directory, run patcher_cf.exe, and you're all set to go.
