I'm trying to launch a modpack using Twitch launcher with forge version 14.23.5.2768, and I get this error message:

Any tips for fixing this are appreciated.
Use Java 8.
How can I install Java 8?
Grab it from java.com.

1. Open the Twitch App
2. Click Settings
3. Click Minecraft
4. Scroll down to Java Settings
5. Use the drop down menu to select Java Version
