Installing the Discord application on your Windows 10 or Windows 11 computer may result in the error message Installation has failed. This post identifies the potential causes, as well as the most effective solution to the problem.

How come I can’t install Discord?

You may receive the “installation failed” error when trying to install Discord if you have one of the following factors:

There is an active discord process running.

When Discord fails to install and you receive the “installation failed” error when you try to reinstall, there may be an active process blocking the installation. In some cases, Discord itself is running this process, in others, it might be another related process. 

Try pulling up the Task Manager (CTRL+ALT+DEL) if you want to find out if you still have multiple instances of Discord running in your machine.

Interference by a third party.

Other apps may be blocked from being installed if certain programs or pieces of software are running. It has been reported in the past that some users have experienced problems installing Discord due to their security software. 

It’s possible that any antivirus or antimalware software you have installed on your PC considers the installer a threat and refuses to launch it.

Incompatible Windows OS settings.

It may be necessary to run Discord in compatibility mode on certain machines. It should run even when this mode is not activated by default, but if you encounter problems after installing Discord, you should check its compatibility first.

Drivers that are out of date.

Occasionally, Discord won’t install if your computer doesn’t have the latest audio hardware drivers.

A driver is the operating system for a particular piece of hardware and is required by Windows to run apps such as Discord. Depending on your audio driver, apps that use your hardware may not function correctly or may refuse to install.

There are damaged files.

There is a possibility that the previous Discord folders or files were not deleted properly, or are still detectable by the system when you try to reinstall Discord. There is also the possibility that the installation files may be damaged.

Installing apps is blocked by the browser.

Your web browser may be running an extension designed to block software downloads if you have configured your web browser to be more secure.

When Discord installation fails for you, it’s almost certainly because the app is running in the background.
