Discord Installation has Failed

What causes the error ‘Discord Installation has Failed’?

After checking various user reports and coming up with experiments of our own, we came to the conclusion that this error message is usually caused by the following factors:

  • Corrupt/abundant local data: If you are reinstalling Discord on your computer after you have removed it earlier, you might have forgotten to remove the local files stored against your profile. These local files usually conflict with Discord when you try to install it again.
  • Antivirus software: Antivirus software is known to block installations of several applications on your computer as a false positive. Disabling them solves the issue.
  • Microsoft .NET Framework: Discord requires that you have the .NET framework already installed on your computer. If the module is not present, you will probably experience this error message.
