By Pranab Sen

✎ Key Points:

» You can address Discord installation failures by finding issues such as corrupted local data or interference from third-party antivirus software.
» Use Control Panel to uninstall Discord, end any related processes in Task Manager, and delete the Discord folder from App Data to ensure a clean uninstallation.

Why Does it Show Installation has Failed on Discord:

There are some reasons for which it does show installation has failed:

1. Previous App data of Discord

If you already have an account on Discord and have downloaded the Discord application on your PC, there are lots of your previous data stored in the “App Data” folder of Discord.

If you wish to uninstall the previous Discord application and re-install it again, your newly installed Discord app’s data is overwritten on the older one. That’s why the glitches will be shown there, and to avoid them, you have first to delete your old Discord app data.

2. Because of Antivirus software

There are some chances that the security software, like third-party AntiVirus software, may block the Discord installation processes. Sometimes, if you have third-party Antivirus software installed on your computer, you can not install Discord on your PC.

If the AntiVirus software is already built on your PC, in that case, the AntiVirus software allows you to install Discord. Still, if you have downloaded third-party Antivirus software for a PC (like Avast), it can show that “Installation has failed on Discord.”

3. Corrupt/abundant local data

If you are re-installing Discord on your computer after you have removed it earlier, you might have forgotten to remove the local files stored against your profile. These corrupted local files usually conflict with Discord when you try to install the application again. 

4. You didn’t allow a few permissions

When you are going to install an application, there are certain permissions that you should give them. Some permissions were asked at the time of installation of the Discord app.

You have to tick them all. If you have not ticked the boxes, you may fail to install the application.
