Steam Call of Duty 4 Owners Please Read:

Information:

On April 27th, 2018 the Steam distribution was updated, changing the games executable from version 1.7.568 to 1.6.13620. While this was technically a downgrade, this was a new 1.6 revision making it incompatible with any remaining 1.6 servers, and certainly not 1.7 servers. Making things immensely more complicated, Activision pushed another update on May 3rd, 2018. Again changing nothing but the executable, this time to an official 1.8 revision (1.8.13620) (not to be confused with the "CoD4X 1.8" client that's been floating around for the last couple years which you should avoid like the plague). Just as before, this update makes the client incompatible with 1.7 servers.

Background:

This was done seemingly as a direct response to this Reddit thread where some users oh-so-helpfully seem to have gotten Activisions attention regarding an ancient and well-known exploit. A point of note here is that the exploit Activision "patched" only effects peer-to-peer games (CoD6-CoD69) not server based games such as CoD4(PC). Whatever else may have been done to the executable is unknown at the time of writing. Not that it particularly matters. The Steam install base represents an incredibly small fraction of the player-base, and with that being the case 1.7 is going nowhere.

Fix:

The fix is relatively simple. download the 1.7 .exe linked below and use it to replace the iw3mp.exe in your install folder. Unfortunately Steam has removed the ability to completely stop a game from receiving updates. However, CoD4 doesn't require Steam to play, so you can simply move the "Call of Duty 4" folder out of Steam's directory and put it literally anywhere else. If you don't want to do this, at least make a backup of the folder, or at the very least the 1.7 executable as there's nothing at all stopping another "patch" from doing this all over again.

You need to be logged in to download the file.

Should probably pin this, put it up as a splash-screen post.

[If you can't see our server, click here.] or something to that effect.

[Gryphus_1]

Which is something I meant to do. Thank you.

Hey Gryph, im not sure what you mean by replace it with the file, do I just delete the Iw3mp file? I only just got the proper steam version and am a little confused with how to get back onto the server again.

what should the 17exe.7z file look like? is it meant to be a compressed file? I have included a picture to show what im talking about.

[Gryphus_1]

The file is compressed and encrypted to prevent any complications. Simply unzip the file using the password listed, and replace Steams "iw3mp.exe".

not quite sure why when i download the file it doesn't download into a zip, it just downloads into a adobe document?

[Gryphus_1]

I didn't realize I made that a .7z file... Not everyone can read those. I'll upload a .zip later today.

Updated. Depending on your browser it may try to keep you from actually downloading it.

Windows cannot complete the extraction.
The destination file could not be created. WTF??

[Gryphus_1]

Sorry, I can't help you there.

Come on Teamspeak tomorrow night and we might be able to work it out.
