If you're seeing an error that says "a JavaScript error occurred in the main process" or "a fatal JavaScript error occurred" when trying to open or install Discord, there are several potential fixes. While these fixes are designed to resolve this error on Discord, they should work to resolve similar errors in other apps, including Microsoft Teams. We'll show you how to troubleshoot JavaScript errors for Discord, Microsoft Teams, and other Windows 10 apps.

  1. 1

    Open your antivirus or antimalware software. If you're unable to install Discord or another app on your PC because of a JavaScript error, such as "a JavaScript error occurred in the main process," your antivirus software may be blocking the installer. You can fix this by adding an exclusion for the installer.

    • If you're using Windows Security, which comes for free with Windows, type security into the search bar and then click Windows Security.
    • The remaining steps will cover unblocking an installer with Windows Security, but your antivirus suite may have different menu options.

  2. 2

    Go to the Virus and threat protection area. This gives you a general overview of your antivirus settings.

    Run the installer again. Once you've allowed the installer to run, you should resolve JavaScript errors that occur during installation.

  1. 1

    Close Discord (or the app you're trying to fix). If you get a JavaScript error when trying to launch or install Discord or another app, the application data may be corrupt. If the app is running right now, you'll want to close it so you can properly delete and reinstall it. Make sure it's not minimized to your taskbar.

    • To be sure it's closed, press Control + Alt + Delete and click Task Manager. If you see a that the app is running, click to select it, and then click End Task.[1]
    • Even if you've only tried installing the app and were not successful, you should still use this method before you try to install again.

    Press ⊞ Win+S . This activates the Windows search bar.

  3. 3

    Type %appdata% and press ↵ Enter . This opens a File Explorer window to your application data.

  4. 4

    Permanently delete the folder for the app you're trying to fix. For example, if you're trying to fix Discord, you'll want to delete the "Discord" folder. Here's how:

    • Hold down the Shift key as you press Delete.
    • Click Yes.

  5. 5

    Open your Windows Settings . If you're getting an error that says "a JavaScript error occurred in the main process" when trying to install Microsoft Teams, this may indicate a problem with the C++ libraries installed on your PC.[2]

    Close Discord (or the app you're trying to fix). If you get a JavaScript error when trying to start Discord or another app, certain processes may be failing because they need more permissions. If the app is running right now, you'll want to close it. Make sure it's not minimized to your taskbar.

    • To be sure it's closed, press Control + Alt + Delete and click Task Manager. If you see a process for the app running, click to select it, and then click End Task.

  2. 2

    Right-click the Discord icon on your desktop or in the Windows menu. A menu will expand.

    Click Open file location . If you don't see this option, you may have to click More first. This takes you to the app's install location.

  4. 4

    Double-click the latest version of Discord. If you've run a few Discord updates, you may have several folders beginning with app- and ending with a number. Double-click the one with the most recent version number.

    • If you're trying to fix a different app, you'll usually see that app right here in the folder you've opened. If not, look around for a file with the app's name—it may end with ".exe."

  5. 5

    Right-click the app and select Properties . Properties for the selected app will appear.

  6. 6

    Click the Compatibility tab. It's at the top of the window.

  7. 7

    Check the box next to "Run this program as an administrator." This gives the app permission to everything on your PC, which may clear up issues caused by access rights.

  8. 8

    Click OK . This saves your changes.

  9. 9

    Start Discord or your preferred app normally. Now that you've set the app to run as an administrator, starting it by double-clicking its icon on your desktop or in the Windows menu will run it with elevated privileges.
