Blém instalation des patchs 1.5 et 1.4 COD 1

Bonjour,

jai un petit problem a chaque foi que je veu installer le patch 1.4 ou 1.5 il me met : setup could not locate instalation of call of duty
since we were unable to locate a valid installation
you will be prompted for the location of call of duty
during the installation
call of duty must be installed before applying the patch

clic to continu é apré : setup could not locate a valid cd key
please re-enter your cd key in the
multiplayer options menu or reinstall
call of duty to correct this problem

( réinstaller la clé du produit dans le menu multi et carrément désinstaller le jeu é le réinstaller ) cela ne marche toujour pas

merci de vos prochaines réactions et en espérent résoudre mon problem
bon jeux a tous amis gamers
