Battle.net is an online gaming social networking service that also doubles up as a digital right management platform for games developed by Blizzard Entertainment. Battle.net is developed by Blizzard Entertainment and it dates to long way back than you probably think, it was launched in December of 1996.

The first ever game ever released on this platform was their in-house game, Diablo. At that time, when it was released, it was quite unique, making online PC gaming smoother and simpler. Many other companies started following the same path. Battle.net was the house for industry hits like World of Warcraft, Diablo series, Overwatch, and of course the Call of Duty games.

But before you proceed any further, to prevent these kinds of problems, we strongly recommend you keep your system up to date. This means having the latest available drivers for your graphic card. Manufacturers optimize your specific GPU for the latest games and push out the drivers regularly, that’s why they’re so important.

Here are the official links from where you can download the latest drivers, Nvidia https://www.nvidia.com/download/index.aspx, AMD https://www.amd.com/en/support, Intel https://www.intel.in/content/www/in/en/download-center/home.html. Also, have the latest available DirectX version for your system, you can find them here https://www.microsoft.com/en-in/download/details.aspx?id=35. It is also recommended to have the latest version of windows installed to avoid such problems.

Okay enough formalities already, I’ll begin with the ways you can get these issues resolved. Here we go!

Fix 1 Disable the game to run as administrator:

By default during the installation itself, the game is set to run with the administrator’s permission. Usually, this is fine, sometimes it’s not, one such case is this one. To make this right:

Open Battle.net launcher > Click on the game you are facing an issue with > Click on the cogwheel that is beside the play button > Select show in folder > Find the .exe > right-click and select properties > navigate to compatibility section > uncheck run as administrator > click apply and select Ok.

Once this process is done, start the game and see if it is up and running. If not so, please proceed to further solutions.

Fix 2 Repair the game:

One reason why this could error might be showing up is you have corrupted or missing game files. It is almost impossible to verify if you’ve got all the files you need or not, but thanks to these modern-day game launchers, almost all of them can scan your game for you to fix it if it has broken or missing essential files.

To do so, Open Battle.net launcher > right-click on the game you want to fix > select options > select scan and repair. It will automatically start scanning all your game files for you and tell if anything is wrong. It will ask your permission if there is anything to fix, go ahead and fix it. Once that is done, check whether you are able to play or not, this should mostly solve your problem.

Fix 3 Update the game and graphics card drivers:

Such bugs and errors are more common than you think, and that is why developers always push out updates from time to time, addressing such bugs and errors. They do their job, your job is to ensure you are using the latest version of the game and drivers are installed on your computer.

You can check and update your game from the Battle.net launcher itself, it’s that simple. If you are running on the latest available version of the game but still facing the issue, then you most probably are running on older graphics drivers. Update them and try again. You can find the direct links to your specific manufacturer’s websites directly from our article itself, I’ve mentioned the links above in the introduction itself, please scroll up.

Fix 4 Change game server region:

Sometimes this issue can be region specific, So what you can do is switch your region and that is doable. As I’ve been mentioning, again and again, Open Battle.net launcher > select the game you want to change region > under game version you can see a globe icon, select it > change it to the region you prefer. Once you have done this, try playing the game and see if everything’s running fine.

Fix 5 Disable launch options:

Sometimes there might have been any additional command lines added to the game. This can disrupt how the game is supposed to work. To remove it open Battle.net launcher > Select the game you want to fix > select the settings cogwheel you see beside the game’s play button > Select game settings > make sure the additional command line arguments box is unchecked. Now try running the game.

Fix 6 Delete cache files:

Call of Duty Warzone3

Almost every program has temporary files present in the cache, they are essential for the program to run as it is intended to. But sometimes the cached data of the program might be corrupted, so the program might misbehave. The only way to fix this is to erase the cache data altogether. You don’t have to worry as these are only temporary files and will be created properly by the program itself again if required. Follow the below steps to erase the cache data:

  • Completely close the Battle.net launcher using task manager, which you can access by pressing Ctrl+Shift+Esc. You have to right-click on the program and click end task.
  • Now open the Windows Run dialogue box, by pressing the Windows Key+ R. Type in %localappdata%.
  • A new window will pop up, now find the folder named Battle.net or Blizzard entertainment. Delete the folders permanently.

Once it’s done re-launch the client and see whether the game works or not.

Fix 7 Turn off anti-virus:

Most of you might be using an anti-virus program, even if you don’t you’ll still have Windows Defender enabled by default. Sometimes these anti-virus programs can be overprotective and trigger false alarms, in one such case, this error might be occurring for you.

So what you can do is turn off whichever anti-virus program you are using temporarily. Then try opening the game. Once you have verified that the game is working or not you have to turn your anti-virus program back on. If it is not working simply enable it again, but if the game is working, then set the specific game as an exception after you have turned the anti-virus back on.

Fix 8 Allow the program through the firewall:

Battle.net requires you to always stay connected to the internet to play the games you have, that is why it is also a DRM platform. To have a successful connection you have to let the program pass through your Window’s firewall. To do so:

  • Open windows search and type in firewall and open the application.
  • Click on change settings.
  • Find the game you are trying to fix and enable it through the firewall.
  • If the program you need isn’t available in the list, you can manually add it, you must select add a new program, then browse whichever executable program you want, and simply click add.
