Is it to create a server as you have posted in server section.
As you have no idea about Cod4x downloads I will assume you have posted in the wrong section and you want to install CoD4x client
I take it you have cod4 installed.
DOwnload cod4x files: https://cod4x.ovh/uploads/short-url/d5Tcz0e3rFBEE20Sw5Ep9wi0RqR.zip
extract to the root of your cod4 directory where the iw3mp.exe is.
Go into the cod4x folder that just extracted and find and run the install.cmd
