What Causes the “Discord Installation has Failed” Issue

When attempting to install Discord, you may receive the “installation failed” error for one of the following reasons:

The Discord Process is Running in the Background

If Discord won’t install and you receive an “installation has failed” error when you try to reinstall it, a current process is likely preventing it. This process could be the Discord app itself or another Discord-related method.

Pull up the Task Manager to see whether there are numerous instances of Discord operating on your computer or other processes related to Discord.

Incompatibility Between Applications

Some programs or pieces of software may prevent other apps from being installed. For Discord, several customers have previously reported that their security software was the most prevalent reason for their installation failing.

If you have an antivirus tool installed on your computer, it’s likely that it detects the Discord installer file as a possible threat and prevents you from running it.

Corrupt Discord Files

If you’re trying to reinstall Discord, but the system won’t let you, it’s possible that prior Discord folders or files were not entirely erased or are still being identified by the system. It’s also possible you’re working with corrupt installation files.

App Version Compatibility Issue

It may be essential to run Discord in compatibility mode on some computers, and Discord should run even if this mode is disabled by default. However, if you have issues opening Discord after installing it, try looking into its compatibility settings.

Outdated Drivers

If your computer does not have the newest drivers, especially the drivers for your audio device, Discord cannot install correctly.

A driver is a piece of software that Windows needs to operate apps like Discord. Applications that use your hardware may not run properly or fail to install if your audio driver is outdated.
