Call Of Duty Modern Warfare 3 Unable To Create Steam Appid.txt.
What is steam_appid.txt?
Steam_appid.txt is a text file that contains the application ID of a Steam game. This file is used by Steam to identify which game you are trying to run and to verify its ownership.

What causes the error "Unable to create steam_appid.txt"?
There are several possible reasons why you may get this error when trying to play Call Of Duty Modern Warfare 3. Some of them are:
You have installed the game in a different location than your Steam library folder. Steam may not be able to find the game files or create the steam_appid.txt file in the correct directory.
You have installed the game previously and when you uninstalled it, you didn't fully delete it or you left the dedicated server installed. Steam may get confused by the leftover files and fail to create the steam_appid.txt file for the new installation.
You have a corrupted or missing steam_appid.txt file in your game folder. This may happen due to a virus infection, a disk error, or a faulty download. Steam may not be able to read or write the steam_appid.txt file properly.
You have a firewall, antivirus, or other security software that is blocking Steam from accessing or creating the steam_appid.txt file. Some security programs may see Steam as a potential threat and prevent it from modifying your files.
How to fix the error "Unable to create steam_appid.txt"?
Depending on the cause of the error, there are different solutions that you can try to fix it. Here are some of them:
Verify the integrity of your game files. This will check if your game files are complete and up-to-date, and will repair any corrupted or missing files. To do this, open Steam and go to your library. Right-click on Call Of Duty Modern Warfare 3 and select Properties. Go to the Local Files tab and click on Verify Integrity Of Game Files. Wait for the process to finish and then try launching the game again.
Move your game folder to your Steam library folder. This will ensure that Steam can find and access your game files easily. To do this, open Steam and go to Settings. Go to Downloads and click on Steam Library Folders. Note down the location of your default Steam library folder (usually C:\\Program Files (x86)\\Steam\\steamapps\\). Then, go to your game folder (usually C:\\Program Files (x86)\\Steam\\steamapps\\common\\Call of Duty Modern Warfare 3\\) and cut and paste it into your default Steam library folder. Restart Steam and try launching the game again.
Create a symbolic link from your game folder to your Steam library folder. This is an advanced solution that involves creating a shortcut that Windows will read as an actual directory. This will trick Steam into thinking that your game folder is in your Steam library folder, even if it is not. To do this, open Command Prompt as an administrator (press Windows + R, type cmd, press Ctrl + Shift + Enter). Type (or copy and paste) the following command: mklink /D \"C:\\Program Files (x86)\\Steam\\steamapps\\Call of Duty Modern Warfare 3\\\" \"\" (replace with the path where you installed the game). Press Enter and wait for the confirmation message. Restart Steam and try launching the game again.
Disable or whitelist Steam in your firewall, antivirus, or other security software. This will allow Steam to access or create the steam_appid.txt file e0e6b7cb5c
