In this article, we have compiled all fixes to the Discord fatal JavaScript error. Scan through the article and try each solution to find one that works for you.

What is Causing Discord JavaScript Error?

Discord issues like the Discord JavaScript error occur for numerous reasons. We cannot point to a specific reason behind this issue. A few common things that may be causing Discord JavaScript error include:

  • Discord app settings: an issue with the installation process is prompting the error. The solution is reset Discord or reinstalling the application.
  • Quality Windows Audio Video Experience service: the service that’s directly related to Discord’s core functionality has been disabled. It usually happens on Windows 7 computers.
  • Discord administrator rights: running Discord as an administrator often brings about the Discord JavaScript error.

Fix 1: Delete Discord Files

Discord stores temporary data in your computer to make general processes faster. Stored data also causes issues like Discord JavaScript error. To make a fresh start, you need to delete the error files and begin the process again.

To delete Discord temporary files:

  1. Press Ctrl + Shift + Esc to open the Task Manager.
  2. Scroll through the list of Apps and Background processes. If you find a Discord-related process, right-click on it, and select End task.
    Important: you will not be able to delete Discord without ending all Discord-related processes from the Task Manager.
  3. Press the Windows + R keys, type %appdata% in the window, and hit enter.
  4. In the AppData\Roaming folder, right-click on the Discord folder and select Delete.
  5. Press the Windows key + R, and in the dialog box, type %localappdata%, and hit enter.
  6. In the Appdata -> Local folder, place the Discord folder, right-click, and select Delete from the menu.

After deleting Discord files, the application should be running smoothly. This solution works not just for Discord fatal JavaScript error, but other issues like Discord update failed, Discord keeps freezing, and more.

Fix 2: Run Discord Without Administrator Privileges

For most Discord errors, we recommend running the application with the admin privileges. However, it’s exactly the opposite in this case. A lot of users have reported that running Discord without admin rights resolved the Discord JavaScript error for them.

To run Discord without the admin privileges:

  1. Locate the Discord executable file or Shortcut, right-click on it, and select properties.
  2. In the properties window, open the Compatibility tab, and uncheck Run this Program as an Administrator.
  3. Click OK to confirm settings and any dialog boxes that appear afterward.

Note: the settings will not apply automatically unless you confirm by hitting Ok.

Now try installing Discord again, and see you’re running into the issue again.

Fix 3: Disable Antivirus

Antivirus is the silent culprit in issues like Discord JavaScript error.

It’s well known that antiviruses often target specific Discord installation files and stop the process in tracks. It usually means that Discord can no longer access or use those files to complete the installation process. Most commonly, the Discord_voice recover file falls victim to the antiviruses.

To resolve the issue, you can disable antivirus and try installing Discord again. If it works, then open the antivirus software and whitelist Discord.

Fix 4: Change The Quality Windows Audio Video Experience Service Settings

The quality Windows audio-video experience services enable audio and video streaming apps to run correctly. In case, the service is disabled, it gives rise to the Discord JavaScript error.

To enable quality Windows audio-video experience services:

  1. Press the Windows key + R, type services.msc, and hit enter.
  2. Scan the list of Services for quality Windows audio-video experience services. Press the Q key on your computer to quickly find the service.
  3. Right-click on the service and select Properties from the menu.
  4. In the Properties -> General tab, check if the Service Status is Running. If it is running, then press stop and then start again.
  5. Before closing the properties window, set the Startup Type to Automatic.

Changing the quality Windows audio-video experience services mostly resolves the Discord JavaScript error in Windows 7.

Here’s how you do it in Windows 7:

  1. Press the Windows key to open the start menu. Right-click on Computer, and click Manage. Administrative privileges will be required to proceed further.
  2. Now, navigate to Server Manager > Features and select Add features (on the right side of the window) .
  3. In the Add Features window, locate and check the box labelled Quality Windows Audio Video Experience, and click Next to proceed.
  4. Confirm the installation and select the QWAVE option.

Restart your computer to apply the change, and see if it resolved the issue.

Fix 5: Reinstall Discord

Fix 6: Refresh Windows Computer Policies

There is one more way to fix the Discord JavaScrip error through your computer’s command prompt. For some users, refreshing their Windows 10 computer’s local Group policy and active directory-based group policies through the gpupdate command worked.

To refresh your windows computer’s policies:

  1. Press Ctrl + Shift + Esc to open the Task Manager, right-click on Discord, and select End Task.

  7. Now, reinstall Discord into your computer.

Important: delete Discord files (fix 1) if you run into the Discord JavaScript error again.

Relaunch Discord and check if the issue is resolved. If nothing has worked, then the issue is probably not related to Discord.
