Update 1.4.382 - Musta1337/TeknoMW3 GitHub Wiki

⚠️ Notice
- Client: You only need the iw5mp.exe and zone\your-language\localized_ui_mp.ff files from 1.4.382
- Server: You only need the iw5mp_server.exe file from 1.4.382
  * All other files must be from the latest version of the game.

The latest version of Call of Duty: Modern Warfare 3 is 1.9.388110, and that's what you get when you download it from Steam. Our mod has been developed for an older version (1.4.382), and thus after installing the game you will need to downgrade.
Unfortunately, the developer doesn't make older versions of the game available, and we can't host the files here because it would constitute copyright infringement.

1. Go to Google (or any search engine).
2. Search for something like this: TeknoMW3 1.4.382 Patch
   • Choose a trusted looking link.
3. Check the file before extracting (or after extracting, the 3 files you will need) in VirusTotal.
   • If there're more than 2 detections, search a better link.
   • Most of them can be packed in RAR or ZIP format, you may need 7-Zip, WinRAR or other to extract the files.
4. Extract only the necessary files to your base game folder (replacing the original files).
   • It's recommended that you make a backup of the original files.

• To verify the Checksum, you can use HashCheck.
  • You will have to move the .md5 file to where you have the Update 1.4.382 files, and open it to start checking them.
• Partial-Checksums.md5
  • The 3 required files in English, German and Italian.

• As you will read across the Wiki, you need the Update 1.4.382 (only 2 files to client and 1 file to server). But one of those files, changes according to the language (localized_ui_mp.ff).
  • Everything because the only error (of not using this file) is "I try to create a class, and all weapons are black / grey".

• ⚠️ Everything you're going to read, it's based on: CoD: MW 3 - Dedicated Server and using only the iw5mp.exe, iw5mp_server.exe and zone\english\localized_ui_mp.ff files of Update 1.4.382.
• The only error that happens when using localized_ui_mp.ff (from the English game) in another language, is the Couldn't load image 'specialty_new' error.
• You could therefore "bypass" that error by making a few small modifications.

• Rename your zone\spanish\localized_ui_mp.ff to localized_ui_mp.ff.bak.
  • If you have the game in Russian, it will be zone\russian\localized_ui_mp.ff...and so on.
• Download Update 1.4.382, copy its zone\english\localized_ui_mp.ff and paste it into your zone\spanish.

• Download and extract the TeknoMW3-MultiLang-Generator.zip.
  • You may need 7-Zip, WinRAR or other to extract .
• Move the 7za.exe and MultiLang-Generator.bat to the main folder.
• Run MultiLang-Generator.bat.
  • With or without administrator, it doesn't matter.
• If everything is OK, you will see that both files were deleted and that you now have an a_MultiLang.iwd file.

• There you go...now everything's supposed to be working perfectly.
  • If it doesn't work, return everything to its original state and try the "Manual Mode".

• Rename your zone\spanish\localized_ui_mp.ff to localized_ui_mp.ff.bak.
  • If you have the game in Russian, it will be zone\russian\localized_ui_mp.ff...and so on.
• Download Update 1.4.382, copy its zone\english\localized_ui_mp.ff and paste it into your zone\spanish.

• Create a backup of your main\localized_spanish_iw00.iwd, since you will edit the original file.
  • If you have the game in Russian, it will be main\localized_russian_iw00.iwd...and so on.
• Open this file with 7-Zip, WinRAR or other.
• Go to the images folder and extract the specialty_new_nonenglish.iwi file.
• Rename the specialty_new_nonenglish.iwi you extracted, to specialty_new.iwi.
• Add this file to your main\localized_spanish_iw00.iwd.
  • Inside the images folder.

• There you go...now everything's supposed to be working perfectly.
  • If it doesn't work, start crying...and download the game in English.

⚠️ Note
- It has been verified that this method works with French and Spanish. ✅

- Unable to verify with Japanese, Polish and Russian. ❗
  * This doesn't mean it doesn't work, I just can't make sure you have to edit the main\localized_XXXXXX_iw00.iwd file.

- You shouldn't follow this guide if you have English, German o Italian. ❌
  * Since you can "quickly" find localized_ui_mp.ff in those languages.
