COD4 not running despite downloading 21.1

i have downloaded everything, cod 4, patch 1.16,1.17 and client 21.1 but it doesn’t run, if i run install.bat it shows the startup of cod4 but doesn’t run, whereas if i uninstall the client the multiplayer starts running, but of course i cant play any servers without it installed

i have a cracked version which i downloaded from the video download guide of promod, it was 6.5 gigs

ps(ive downloaded the pb files too)
