2. Extracting the necessary files without installing:
=================================================
Recommended only for System Administrators and advanced users. It is possible to extract the necessary files without running the installer. To do so, simply open the update using any unzip program. Once you have it open, you´ll want to replace these original files (located in the RtCW root folder) with the new versions located in the update:
Anet.inf
CGAME_MP_X86.DLL
QAGAME_MP_X86.DLL
UI_MP_X86.DLL
Wolfmp.exe
