2. Search for **Java 8** in the list.
3. Select it and press **Uninstall**.
4. Follow the confirmation prompts until it's entirely removed.

<p class="callout warning">If you have other versions of Java installed, you may need to uninstall them or select the correct Java version in the relevant launcher settings.</p>

1. Open the CurseForge launcher.
2. Select the settings cog on the bottom left of the launcher.
3. Select **Minecraft** and scroll down to **Java Versions**.
