3 Easy Solutions to Fix Discord “Installation has Failed” Error

Let’s begin with three easy solutions. Though they may seem simple, they’re quite effective in resolving the error. Starting with these basic solutions is often the quickest way to solve the issue before trying more complex ones.

Solution 1: Re-download the Discord Setup File

Fix Your PC Advanced SystemCare will automatically clean up, speed up & fix your Windows issues and make Discord installation possible.

First, try getting a fresh copy of the “DiscordSetup.exe” file. This is to make sure that the problem isn’t happening because the setup file got messed up. 

Just go to the Discord website at https://Discord.com/download and click on “Download for Windows” to download a new Discord installer. Then, try to install Discord again using this new setup wizard.

Solution 2: Run the Discord Setup File as Admin

  • Press the ‘Windows Key’ on your keyboard.
  • Type “Discord” and look for “DiscordSetup.exe” in the search results.
  • Click on “DiscordSetup.exe” and choose “Run as administrator”.

  • Click “Run” to start installing Discord. Discord should now install without any problems. If you still have issues, try the next solution.

Solution 3: Temporarily Disable Antivirus and Firewall

Disabling antivirus and firewalls temporarily can prevent them from interfering with the installation process. Sometimes, these security measures mistakenly identify Discord as a threat and block its installation. Here are steps for both Windows security and third-party software:

If you’re using “Windows Security”, follow the below steps:

  • Press the ‘Win + S’ keys and type “Windows Security”, then press ‘Enter’. 
  • Select “Virus & threat protection”.

  • Temporarily turn off these features.

  • Windows Security or antivirus software is now turned off. Try installing Discord again to see if it works this time. Once the installation is successful, remember to turn your security software or Windows Security back on to keep your computer protected from threats.
