Since Activision released Call of Duty: Warzone, many COD players have joined this new battle royale game, making it one of the most popular games in 2020. However, Warzone seems to be having bugs and crashing a lot, especially on PC. Gamers have been reporting the game won’t even launch yet there aren’t many solutions. If you’re on the same boat, we’ve put together some fixes for you!

How do I fix it?

Not all solutions are necessary, just work your way down until you find the one that does the trick!

1: Make sure your PC meets the minimum specifications for Warzone

2: Run as administrator

3: Update your graphics card drivers

4: Verify the integrity of your game files

5: Make sure your system is up-to-date

6: Allow the program through firewall

7: Perform a clean boot

8: Reinstall Warzone and/or the Battle.net app

Before we dive into anything advanced, make sure to restart your PC as well as the game to see if the problem persists.

Fix 1: Make sure your PC meets the minimum specifications for Warzone

The first thing you want to check is if your PC meets the minimum requirements for Warzone, which also applies when you play any large-scale game.

The minimum specifications:

OSWindows 7 64-Bit (SP1) or Windows 10 64-Bit
CPUIntel Core i3-4340 or AMD FX-6300
RAM8GB RAM
HDD175GB HD space
VideoNVIDIA GeForce GTX 670 / GeForce GTX 1650
or Radeon HD 7950
DirectXRequires DirectX 12 compatible system
NetworkBroadband Internet connection
Sound CardDirectX Compatible

If you want a smoother gaming experience, check out the recommended specifications:

OSWindows 10 64 Bit (latest Service Pack)
CPUIntel Core i5-2500K or AMD Ryzen R5 1600X processor
RAM12GB RAM
HDD175GB HD space
VideoNVIDIA GeForce GTX 970 / GTX 1660
or Radeon R9 390 / AMD RX 580
DirectXRequires DirectX 12 compatible system
NetworkBroadband Internet connection
Sound CardDirectX Compatible

If your PC specifications are sufficient but Warzone still won’t launch, move on to the next solution.

Fix 2: Run as administrator

Sometimes your game needs enough permission to run properly. Try to run the program as administrator: it gives the program administrator privileges while launching, and only takes two clicks. Here’s how:

  1. Right-click the Battle.net icon on your desktop, then click Run as administrator.
  2. Log on to your account and launch the game.

If this doesn’t solve your problem, try the next solution.

Fix 3: Update your graphics card drivers

Some gamers have been able to solve the not-launching issue by updating their graphics card driver. An outdated or faulty driver can actually cause a lot of problems, so you want to make sure your graphics card driver is up-to-date and functioning properly.

There are two ways you can get the right driver for your graphics card: manually or automatically.

Manual driver update – You can update your graphics card driver via Device Manager. Go to the manufacturer’s website, and search for the most recent correct driver. Be sure to choose only drivers that are compatible with your Windows version.

Automatic driver update – If you don’t have the time, patience, or computer skills to update your drivers manually, you can, instead, do it automatically with Driver Easy. Driver Easy will automatically recognize your system, find the correct drivers for your graphics card and your Windows version, and download and install them correctly:

  1. Download and install Driver Easy.
  2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
  3. Click the Update button next to the flagged graphics card driver to automatically download the correct version of it, then you can manually install it (you can do this with the FREE version).

    Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version which comes with full support and a 30-day money-back guarantee. You’ll be prompted to upgrade when you click Update All.
  4. Restart your PC for the new driver to take effect.
The Pro version of Driver Easy comes with full technical support. If you need assistance, please contact Driver Easy’s support team at support@drivereasy.com

Check if the problem persists. If this doesn’t work for you, try the next solution.

Fix 4: Verify the integrity of your game files

One of the possible causes that you can’t run the game is the game files being damaged. The good news is that you can verify the game files and do a repair if needed within the Battle.net app. Follow these steps:

  1. Open the Battle.net client and go to the Warzone page.
  2. Click the gear-shaped icon, then click Scan and Repair.
If you own Modern Warfare and have been accessing Warzone from MW, you could go to the MW page and do as Step 2 above instructs.

Once the process is complete, you can run the game to see if the problem persists. If this doesn’t give you luck, move on to the next solution.

Fix 5: Make sure your system is up-to-date

If your Windows system isn’t updated regularly, then it’s possible that some system settings are no longer compatible with the game. You can check for the latest Windows Update and install it by following the steps below:

  1. In the search bar next to the Start button, type windows update and click Windows Update Settings.
  2. Click Check for updates.
  3. Install any updates from the scan results.
You may be prompted to reboot during the updating process. Make sure to save your work and important files in advance.

Check if the problem persists. If so, try the next solution.

Fix 6: Allow the program through firewall

The Windows Defender Firewall may not have given permission for the Battle.net app, causing the game launching failure. You can allow the program through firewall with the following steps:

  1. In the search bar next to the Start button, type firewall then click Firewall &network protection.
  2. Click Allow an app through firewall.
  3. Scroll to find your Battle.net Launcher. If you don’t see it, click Change settings.
  4. Click Allow another app.
  5. Click Browse.
  6. Locate the launcher file which should be in the folders that you set up during installation. It’s usually in the C/Program Files(x86)/Battle.net folder.
    Select Battle.net Launcher.exe then click Open.
  7. Click Add.
  8. Check Private then click OK. It means Battle.net is allowed through firewall in a private network such as your home Wi-Fi.
    It should be enough unless you plan to play the game using a public network, which we don’t recommend out of security concerns.
If you’re also using a third-party antivirus software, you could try to temporarily disable the software then run the game to see if this helps. Be extra careful about what you download from the Internet when your PC is NOT under protection.

Launch the game to see if the problem still persists. If the problem returns, move on to the next solution.

Fix 7: Perform a clean boot

A clean boot will start your PC with the minimum sets of drivers and services that Windows requires to run. You can identify if there’s any background program interfering with your game with a clean boot. Here’s how:

Performing a clean boot:

  1. In the search bar next to the Start button, type msconfig then click System Configuration.
  2. Under the Services tab, check Hide all Microsoft services, then click Disable all and OK.
  3. Switch to the Startup tab, click Open Task Manager.
    (Windows 7 users: right-click anywhere empty on your taskbar to find the option of task manager.)
  4. Under Startup tab, click each startup item then click Disable until you’ve disabled all startup items.
  5. Restart your PC. If the problem is gone, then it means some program(s) you disabled in the above steps caused the not-launching issue.
    You can continue to find them out according to the steps below. However if the problem persists, skip to the last solution.

Identifying the problematic program:

  1. In the search bar next to the Start button, type msconfig then click System Configuration.
  2. Under Services tab, check Hide all Microsoft services and the first five items. Then click Apply and OK.
  3. Reboot the computer and launch the game to see if it’s working now. This will allow you to identify if these items caused the Warzone launching failure.

    NOTE: We recommend testing five items in a group since it’s more efficient, but you’re welcome to do it at your own pace.

  4. Repeat Step 2 and 3 above until you find the one that conflicts with Warzone.
  5. If you didn’t find any problematic services, then turn to the startup items. Right-click anywhere empty on your taskbar and click Task Manager.
  6. Switch to Startup tab, enable startup items in a group of five.
  7. Reboot your PC then run the game to see if the problem persists. Repeat Step 6 and this step until you find the item that conflicts with your game.
  8. Disable the problem program and reboot your PC.

You’ll be able to launch Warzone now.

Fix 8: Reinstall Warzone and/or the Battle.net app

Reinstalling a game with a large size can be frustrating, we get it. Since it actually helps many players tackle the launching failure, we would still recommend reinstalling Warzone and/or the Battle.net client if other solutions couldn’t help.

To reinstall Warzone:

  1. Open the Battle.net client and go to the Warzone page.
  2. Click the gear-shaped icon, then click Uninstall.
  3. Once Warzone is uninstalled, click here to re-download the game.
  4. In your downloads folder, double-click the Warzone installer and follow on-screen instructions.

Check if the problem returns. If it does, you may try to reinstall the Battle.net app as well. (This is optional but we recommend doing so.)

To reinstall the Battle.net client:

  1. On your keyboard, press the Windows logo key and R at the same time to invoke the Run box.
  2. Type appwiz. cpl, then click OK.
  3. Select Battle.net, then click Uninstall/Change.
  4. Click Yes, Uninstall.
  5. Once the Battle.net app is removed from your PC, click here to re-download the Battle.net installer.
  6. In your Downloads folder, double-click the Battle.net installer and follow on-screen instructions.

Run the game to see if the problem has been solved.

According to Activision, Modern Warfare owners can’t uninstall Warzone from MW itself. You could make modifications to other game contents though.
