Minecraft and Twitch are among the most popular sandbox video games and streaming platforms. However, if you use the Twitch client to install Minecraft, you may encounter the Twitch add-on installation error and the Minecraft installation error.

This error can occur due to a glitch in the Twitch client or incorrect twitch configuration for add-ons and Minecraft.

Running Twitch as an administrator

For security reasons, Windows has a policy that if an application that does not run as an administrator is not the main application, they cannot communicate with each other. This can prevent certain parts of the Twitch application from working as they should, such as Push to Talk (PTT) and in-game overlay.

If you are having problems, you may be running your game as the administrator, but not the Twitch application. The Twitch application must be running as an administrator for these features to work properly. It is relatively easy to fix this.

Uninstalling and Reinstalling Twitch

  • Select Control Panel from the Windows Start menu.
  • For Windows 7, under Programs, click Uninstall a program.
  • Scroll down to Twitch and click the Uninstall/Edit button on the toolbar.

Increasing Java Memory Allocation

  • Start the Twitch client.
  • Go to File > Settings and open Minecraft.
  • Go to Java Settings > Maximum Memory Allocation.
  • Set it to 7500MB and click OK to save the changes.
  • Then go back to File > Settings and open Addons.
  • Set the backup space to 10MB.
  • Save the changes and restart the Twitch client.

The add-on installation error may occur if the Twitch client is incorrectly configured. Several users reported that changing the size of the allocated memory and the backup settings of the addon helped them solve the problem.
