Fix: Discord JavaScript Error

Are you getting a Javascript error in Discord? Does the error say "A Javascript error occurred in the main process" or something similar? Here is the fix.

Discord is lightweight and easy to navigate, but of course, errors can come up once in a while, which can be pretty annoying, especially if you were planning to chat with your friends or classmates.

Often, a JavaScript error can pop-up either while installing the app itself or while trying to launch it.

The dreaded Discord Javascript error

You can fix this in several different ways, but you may have to go through each individually to resolve the issue properly.

Installation JavaScript Error

If you are having trouble installing the application itself, here is what you will need to do.

Fix 1: Redownload Discord

The most logical explanation why Discord’s installation would cause a JavaScript error is because the file itself is corrupted. Therefore, something likely went wrong during the download.

To check if that is the real problem just download the setup again from the official Discord website and try again.

If you are still getting the same error your anti-virus may be blocking you from accessing the file.

Fix 2: Make an Anti-Virus Exclusion

The anti-virus software on your computer might be the cause of this JavaScript error. To stop that from happening, you will need to add an exclusion in the anti-virus. We can help!

Here’s how to do that with Windows Security (Windows Defender previously):

  1. Search and open Windows Security from Start Menu
  2. On the left-hand side of the window, select Virus & threat protection
  3. Under Virus & threat protection settings, select Manage settings
  4. Scroll down until you find Add or remove exclusions
  5. Click Add an exclusion and pick File
  6. Go to your download folder and select DiscordSetup.exe.

Alternatively: At step 5, exclude the entire download folder and skip step 6.

If you’ve followed every step of the process correctly, the Discord setup is now excluded from the anti-virus software, and you should be able to install it.

Keep in mind; every anti-virus software has a different method for adding exclusions. You can use the guide on the official website of the anti-virus to see what you need to do to add an exclusion.

Discord Launch JavaScript Error

When getting a JavaScript Error while launching Discord, relax! Try these fixes:

Fix 1: Delete Roaming and Localappdata Cache

Windows constantly stores the cache in the Roaming and Localappdata folder to make running certain programs and apps smoother and faster. Like any other application, Discord stores this same kind of temporary data in those two folders.

Over time, some of that data can become corrupted, causing you to have that JavaScript error when trying to launch it.

To resolve this problem, you may have to clear your computer of those cache files.

  1. Close Discord completely from the Tray Icon on the taskbar or through Task Manager
  2. Press Win + R, type %appdata% and click run
  3. This will take you directly into the Roaming folder, where you will need to find the Discord folder and delete it.
  4. Press Alt + Up Arrow. This is going to take you one folder back into App Data. From here, open the Local folder.
  5. Again, find the Discord folder and delete it
  6. When you are done, run Discord

If you have thoroughly followed every step of this fix, you shouldn’t be getting the JavaScript error anymore.

Fix 2: Reinstall Discord

Removing cache and temporary files is similar to reinstalling the application, but you should try reinstalling it either way if that didn’t work.

  1. Open Start Menu, type, and open Remove Programs
  2. Here, you will need to search for the Discord app and then select Uninstall
  3. While it is uninstalling, go to the official Discord website and download the setup
  4. Launch the setup and follow the installation process.

By following our comprehensive guide and going through with every one of these handy fixes, you will effectively eliminate any issues you had with Discord in the past, including the JavaScript error!
