The Minecraft Forge modding API and loader provides players with new ways to play Minecraft. However, some players have said in forums that Forge doesn’t install for them.

Some of those cite a Forge install error message that states, These libraries failed to download.

Note that Forge only works for the Java version of Minecraft. So, players can’t install Forge for the Minecraft MS Store app. These are potential resolutions for players who can’t install Forge for Minecraft Java.

What can I do if Minecraft Forge is not installing properly?

1. Update Minecraft Java to the latest version

  1. Open your Minecraft Launcher app.
  2. Click the drop-down menu to the left of the Play button.

  4. When you’re sure your Minecraft game is the latest version, download the latest Forge version from the Forge website.

Note: The Forge version you download and try to install must match your current Minecraft Java game version. Minecraft displays its version number at the bottom left corner of its menu screen.

2. Restart your internet router
