CoD4 x Issue

Nope but i would download the cod4x files again and reinstall. See if that cures it. You might have a corrupt file

Did that -

No, never had that Roger

Have you tried, uninstalling cod4x then restart your PC. Install cod4x again.

Used the CoD4x uninstaller - noticed most of the files were still present after that so manually deleted all CoD4x files - re-started PC, re-installed CoD4x and same message !!

Not that it helps, i had to reinstall the game as it refused to play 1.7 servers. not tried since

Try deleting World at war and then Elder scrolls on line.

CoD 4 won't run alongside girly games.

wrong version of the 1.8..

Remove your aimbot and try again...

Seriously though, have you installed any other game, program or update prior to this happening?

ok - running 1.7 - deleted everything, re-installed Cod4 and CoD4x annnnnnd same message !!

try this m8 1. Install the following patches first:
Patch 1.6
Patch 1.6-1.7
2. Download the CoD4X 1.8 patch and unpack it in CoD4's directory.
3. Then start the "install.cmd"

5. Copy the downloaded iw3mp.exe to your CoD4 folder and start the multiplayer version with this EXE file.

Are you running cod4 through steam?

Not running the steam version -

Hmmmm runs fine in safe mode, so must be a conflict, should be fun trying to find that, thank you for the help/suggestions

well if mine does that I would freak out

I hope you get to the bottom of it

A bit of a long shot but are you logged in to steam when trying to launch?

If not do so and try again.

I had error messages as well even though it's not the steam version

yeah - tried with steam on and off, working at the moment, turned off a lot of things using the system config tool, just need to go through them all now and try to work out which service/program is causing the conflict.

run in administrator try it

tried that Chris - no difference

Here is how to fix this patch:

Download the file from this site here: https://eu.cybergamer.com/files/6412/

This is the main and original game executable from CoD4 1.7.

When done locate your CoD4 installation, there are 2 ways to find it. If you know where you Steam folder is you can find it on this way:

Open a new Windows Explorer Window. Go to your "Steam" folder (Which is likely in "C:\Program Files(X86)" then click on "steamapps" then "common" and then "Call of Duty 4". Here you got to your CoD4 folder.

Just in case you didn't find your CoD4 folder here is another way:

Open the Steam main window, then click Library, Games. Find in the left list "Call of Duty 4: Modern Warfare". Rightclick the game and choose properties. In the new window click on "Local Files" and then "Browse Local Files". Now you should be in your CoD4 folder.



Since you have now your CoD4 folder locate the file iw3mp.exe. Right click onto it and chose "Delete" and confirm it.

Now go to your before downloaded file then drag and drop it into your Cod4 folder.

Here you should be done with the guide. A reinstallation of CoD4X shall not be necessary as it remains installed even after the Steam update. It just does not activate in case the "iw3mp.exe" file gets replaced.
