Discord is a popular communication platform that allows users to chat via image, text, audio, or video. It is especially useful for the gaming community, but its reach has expanded to other sectors as well, such as education and business.

The thing is, as with any other program, you might run into problems when using the Discord app. So, if you encounter the Discord JavaScript error while trying to install or launch it, don’t worry. You are not alone. Several users have reported receiving the JavaScript error that’s also known to affect other messenger apps like Skype.

In our post today, we’ll share the ultimate guide on how to stop getting a JavaScript error on Discord. Hopefully, one of these solutions will work, and you should get back to using the program without issues.

We recommend that you try the solutions one after the other until you find one that works for you.

What Does the “A JavaScript Error Occurred in the Main Process” Message Mean?

JavaScript error messages can be annoying and frustrating, especially for the casual user. Usually, this happens when a script in a web page or app fails to execute correctly, probably due to an error.

As mentioned earlier, the Discord JavaScript error shows up when you try to launch the app or while using it. Typically, a window displaying the “A JavaScript error occurred in the main process” message will pop up afterward.

Other parts of the error message will also be displayed, showing the affected path or the source of the problem. Usually, the information might be too complicated for an ordinary computer user to comprehend, but it serves significant importance to tech experts.

Unfortunately, it is not easy to determine the exact causes of this error. However, some of the possible scenarios include:

  • Running Discord with administrator permissions
  • The Discord app or its settings may be corrupted
  • The ‘Quality Windows Audio Video Experience’ service, which is related to the core functionality of Discord has been disabled.

How to Fix the Discord JavaScript Error on Windows 10

Solution 1: Delete Discord Files

These troubleshooting technique works with many programs, especially when you suspect that the app’s files could be corrupted. Usually, when you install a program like Discord on your computer, it stores temporary files that enable it to function correctly.

When these files get corrupted, the program associated with them won’t run properly. So, our first step involves resetting Discord settings by deleting folders in the “%AppData% and %LocalAllData% directories.

Here are the instructions:

  1. Exit Discord in the system tray and terminate all processes related to Discord via Task Manager.
  2. Next, open File Explorer, select This PC, and navigate to the path:
  • C:\Users\<Username>\AppData\Discord
  1. If you don’t see the AppData folder, click the View tab on File Explorer’s ribbon, and check the Hidden items box. This will reveal some of the files and folders that Windows intentionally keeps hidden. Alternatively, press the Win + R keyboard shortcut, type “%AppData%” (no quotes) in the Run box and hit Enter.
  2. Now, once you find the Discord folder in the AppData folder, go ahead and delete it.
  3. Next, open the Run box again using the Win + R shortcut keys or right-click Start and select Run from the list of options that appear.
  4. Type “%LocalAppData%” (no quotes), and press Enter or click OK.
  5. Find the Discord folder and delete it.

Once you are sure that all files associated with the Discord app have been deleted, try to launch it to check if it works.

Solution 2: Run Discord Without Administrator Permissions

Generally, most programs require administrator rights to work properly. However, in Discord’s case, it might be the opposite. Some users reported that running Discord without logging in using their administrator accounts resolved the “A JavaScript error occurred in the main process of Discord” error message.

To do so, follow these simple steps:

  1. Locate the Discord icon on your desktop, right-click it and open its “Properties”.
  2. In the “Discord Properties” window, open the “Compatibility” tab, and uncheck the box next to “Run this program as an administrator”.
  3. Click OK > Apply to apply the changes, and exit the window. If you encounter any dialogs, be sure to confirm them for the changes to take effect.

Now, check if you still encounter the Discord JavaScript error when you try to run it. If you do, try the next solution.

Solution 3: Set the Startup Type of the Quality Windows Audio Video Experience Service to Automatic

The Quality Windows Audio Video Experience service enables audio-video streaming applications like Discord to run properly. Therefore, if the service is not running, Discord might run into the JavaScript error.

Check if the service is running, and if not, set the Startup Type: to Automatic.

Here’s how:

  1. Press the Win + R shortcut, type in “services.msc” (no quotes) in the Run box, and hit Enter.
  2. Search for the Quality Windows Audio Video Experience Service from the list on the Services window. To quickly do so, try pressing the letter Q on your keyboard.
  3. Once you find it, right-click it and select Properties or simply double-click it to open its properties window.
  4. From the Properties window, you will be able to see if the service is running by checking the Services status option below Startup Type. If it shows Running, click Stop and then click Start to run it again.
  5. Be sure to change the Startup Type to Automatic before applying the changes.

Now run Discord and check if the problem persists. If it does, check out the next solution below.

Solution 4: Check if Your Antivirus is Causing the Issue

In some cases, your antivirus program might quarantine some specific files that may interfere with the launching of Discord. In turn, the program may no longer access the files. When this happens, it displays the JavaScript error message.

To resolve this problem, all you need to do is add Discord to your antivirus program’s exception list. To do this, access your antivirus application, and check if any Discord files have been quarantined. Note that the process may differ depending on the antivirus software that you are using.

If you can’t grasp how it is done, refer to your antivirus manual. If you don’t find any files blocked, then the problem lies elsewhere. In that case, continue with the next solution.

Solution 5: Reinstall Discord

If all else fails, reinstalling Discord is your last resort. This method is effective because you will install a fresh copy of the program, which means replacing all the files and settings of Discord. For this process to be successful, be sure to log into your administrator account since you won’t be able to uninstall programs using a non-administrator account.

  1. You can uninstall Discord via Control Panel or the Settings app. To proceed, go to your Start menu, search for Control Panel, and run it. You can also click the gear icon to open Settings.
  2. Locate Discord from the list of installed programs and click Uninstall.
  3. You should see the Discord wizard, which will guide you through the uninstallation process. Click Yes when prompted to choose whether you want to “completely remove Discord on your computer.”
  4. When the process is complete, click Finish.
  5. The next step is to install Discord afresh. That means visiting the official Discord website, downloading the program, and installing it on your computer. Follow the on-screen instructions to ensure that you install it properly.

You should now be able to launch and use the program without running into the JavaScript error.
