Clear Steam’s Data Cache
If you recently purchased Call of Duty: Modern Warfare II on PC and are experiencing this difficulty when attempting to launch the game using Steam, you may encounter this issue.
There are some cases where Steam won’t let you play a game you already paid for because it can’t verify that you possess it. Follow our instructions to fix this problem:
- Go to the Steam settings and then Downloads.
- Choose the Clear Download Cache options and wait for it to finish.

To verify the integrity of game files, follow these steps:
- Launch Steam while logged into the account experiencing the problem.

- To continue, select Yes when prompted and wait till the process has finished.
- Please note that it is not uncommon for some files to fail. When this happens, it’s usually because the scan found some files that shouldn’t be changed. If the problem still persists after the system has finished booting up after an integrity scan, try restarting the machine.
Clear Battle.Net’s Data Cache
It’s important to realize that a corrupted cache folder is rather prevalent among PC COD gamers who use the Battle.net launcher to launch Call of Duty: Modern Warfare II. Remember that Battle.Net does not provide a software solution for properly maintaining the cache folder; you will need to perform the cleanup yourself by deleting the Blizzard Entertainment folder from ProgramData after making sure that no conflicting process is using it.
To learn how to clear the cache folder on your Battle.net launcher, please refer to the detailed method below. Please take note that the following guidelines are compatible with any recent Windows release.
- Make sure that no other Blizzard applications or Battle.net are currently active on your computer. Take note that this applies to any and all games and related applications.
- Then, launch Task Manager by pressing Ctrl+Shift+Enter. If the simplified version opened up on its own, press the More Details button.
- After you’ve launched the Task Manager’s advanced user interface, click the Processes tab.
- The next step is to examine the list of processes to see if any Battle.net agent or Battle.net Update agent processes are active. If so, right-click on them and select “End Task” from the option that appears.
- After you’ve ended all programs that could cause problems, you can launch the Run dialogue box by pressing the Windows key plus R.
- To access the cache directory, type “%ProgramData%” into the Run field and hit Enter
(ProgramData).
- After entering the hidden ProgramData folder, look for the Blizzard Entertainment and Battle.Net folders containing your cached Batte.Net data, and delete them using the right-click menu.
- After erasing the two directories, try starting Battle.net again and then launching Call of Duty: Modern Warfare again to see if it resolves the issue.
