Discord Error Fix (3)

1. Firstly, go to the AppData location on your computer by opening the File Explorer and snapping to This PC. The folder directory example is provided, C:\Users\UserName\AppData\Discord

2. If you cannot find this directory the reason is that this folder might be hidden so you may need to switch on the option that allows you to view hidden files and folders.

3. Snap on the View toolbar on the File Explorer menu and check the Hidden items checkbox in the Show/hide segment. Delete all files from the Discord folder in the AppData directory.

4. However, if you see a message asserting that some files couldn’t have been deleted because they are currently in use, try exiting all Discord applications and ending its processes in Windows Task Manager.

5. Now, onto the deletion of files from %localappdata% folder. Use Win + R key combination to launch the Run application then type in %localappdata% and click enter to open the provided directory. Find the Discord folder in the local AppData folder and delete the Discord folder.

6. Verify that the files in folders %AppData% and %LocalAppData% are deleted and that there are no files in them.

7. Restart your PC, open the Discord app to see if the error still appears. Probably, the error won’t appear, and the Discord app will launch.

Solution 2: Whitelist the Discord app installation files from the installed antivirus software

A lot of Antivirus programs target application files that are crucial in the functionality of that software to operate properly. Antivirus programs occasionally target some discord files — particularly the Discord voice application-specific approximate recovery file classifying them as security threats during the Discord app’s launch.

In this circumstance, whitelisting the software from the antivirus software is the most suitable solution. Here we explained the steps to whitelist Discord in the AVAST Antivirus software, but steps should be similar for other antivirus software:

1. Open Avast Antivirus by right-clicking on the Avast icon in the system tray and choosing the open Avast User Interface option from the panel.

2. Navigate to the Protection section and click on the Virus Chest tab.

3. Any quarantined files will show up in the Virus Chest. Here, find any files beginning with discord_ in the virus chest. Click on the three dots option on the right of the quarantined threads list and choose Restore and add the exception option.

4. Do the same step for every file with discord_, and after performing it for all threads in the virus chest, restart the installation process in the end.

5. To make sure that you will not encounter this issue in the future, we recommend that you can also add the Discord executable setup file as an exception in the Avast antivirus software. You can add exceptions by going to settings>general>exceptions and then add exception.

6. For Windows Defender, open the Windows Security from the system tray and choose Protection History below the Scan option, and you can see a list of threads. We can also whitelist the Discord files from there by simply right-clicking and choosing to allow them on the device.

2. Once the task manager is running, locate all the Discord processes, click on them, and right-click and select End Task.

3. Now try a clean installation of Discord and see if the problem is fixed.
