Possible fixes for “0x887a0005 error code” in Modern Warfare 3

As mentioned, there are no solid solutions that you can use to fix the 0x887a0005 launch error code in Modern Warfare 3. However, here are some workarounds that may deal with the issue to an extent:

---

1) Run the game as an administrator

One of the more popular fixes to the 0x887a0005 error code is to run the game as an administrator. To be able to pull it off, you will need to make your way to the file directory of the game and then look for the COD MWIII.exe file.

Now right-click on it and make your way to Properties. There, under the Compatibility tab, you will need to enable “Run this program as an administrator” and then hit Apply.

Once done, you will need to select the Run as an administrator option and then start the game. This is more than likely going to fix the launch issue that you are having with Modern Warfare 3.

2) Verify file integrity

MW3 might not be launching because there are a few corrupt files in your installation directory. To fix it, you will need to make your way to the Steam or Battle.net client and do the following:

Steam Users:

• If you are on Steam, you will need to make your way to the Library and then right-click on Modern Warfare 3. Now go to Properties, and under the Local Files tab, you will need to verify the integrity of game files.

Battle.net users

• Battle.net users can simply click on the cog icon beside MW3 and then click on “Scan and Repair”.

For both clients, this method will start a process that will go over all the files in the installation directory and fix the ones that may have been damaged.
