So after much trial and error and some wasted disks here is how I made it work 100%....
1. Install the game (I installed it from Steam so I would have the
latest version of the game).
2. Download the two attachments listed below (the "Call of Duty MW2
8.5.7.4.7z" in the original post is not needed).
Call of Duty MW2_NewInterface.7z (12.50 MB; ALL FILES NEEDED!)
http://fileforums.com/attachment.php...9&d=1356985934
Extract the files into a temp directory.
Call of Duty MW2_NewInterface.7z (12.74 MB; ONLY NEED SETUP.DLL)
http://fileforums.com/attachment.php...8&d=1356918292
Extract only the "Setup.dll" file into the same temp directory.
This file may not be needed, but it doesn't seem to hurt anything.
3. Install "Inno Setup (Unicode).exe". Open "InstallerScript.iss".
Edit the following line, according to the current installation
directory of the game (where the game is currently installed into).
NOTE: If there is a ";" at the beginning of the line, remove it!
#define ProgramFiles "C:\Program Files\Activision\Call of Duty Modern Warfare 2"
The installed Steam version is here:
#define ProgramFiles "C:\Program Files (x86)\Steam\steamapps\common\Call of Duty Modern Warfare 2"
Click "Save", then click "Compile" to compile the script.
4. This step is only info for us newbies to help learn this stuff. You do not have to do it.
If there is no "Autorun.exe" file in the first .7z (there is one),
open "LangScript.iss", click "Compile" to compile the script.
5. Move these to the "\Compiled\DVD1" folder:
Autorun.exe
Setup.ini
Setup.dll (From the original NewInterface.7z file)
Setup.cab
Setup.exe
Setup-1a.bin
Setup-1b.bin
Setup-1c.bin
Move these to the "\Compiled\DVD2" folder:
Setup-2a.bin
Setup-2b.bin
Setup-2c.bin
Move these to the "\Compiled\DVD3" folder:
Setup-3a.bin
Setup-3b.bin
\Redist (The installed Steam version has this folder here: C:\Program Files (x86)\Steam\steamapps\common\Call of Duty Modern Warfare 2\Redist)
6. Edit the "\Compiled\DVD1\Setup.ini" file, near the end of the file
change these two lines:
LaunchCom1=Redist\DirectX\DXSetup.exe
LaunchCom2=Redist\vcredist_x86.exe
To these:
LaunchCom1={src}\Redist\DirectX\DXSetup.exe
LaunchCom2={src}\Redist\vcredist_x86.exe
7. Make a folder named \Crack (it doesn't matter what you name it),
and copy any game cracks, patches, cheats etc into it.
8. Burn the contents of the \DVD1 \DVD2 \DVD3 folders to 3 DVD5 (4.7gb)
disks with the labels you want.
[The original labels are "Disk_1" and "Disk_2"]
Total sizes: Disks 1&2 4.36 GB, Disk 3 2.33 GB
NOTE1: The install folder cannot be changed at install time (I'm not sure how to change it), it always gets installed into
C:\Program Files (x86)\Activision\Call of Duty Modern Warfare 2
NOTE2: The savegames in Windows 10 get saved into:
C:\Users\YOURUSERNAME\AppData\Local\VirtualStore\P rogram Files (x86)\Activision\Call of Duty Modern Warfare 2
