The Twitch launcher is failing to install Forge correctly and this file isn't being built. The current solution is to install this version of Forge manually.
To do this, you'll need to know:
- Which version of Forge the modpack is using
- The install location that the Twitch App uses for minecraft
This will allow you to:
- Here we can see in the message values that the file forge-1.14.4-28.0.55-client.jar is missing which tells us that it was trying to install Forge version 28.0.55. Download the modpack profile and inspect the manifest.json. To download the profile: Search for the modpack in the Twitch app and click on it to view the details.
- I've read online that Jar Launcher has a hard time opening some java files, but I need to open one for an online school program I'm doing.Whenever I click on the.jar file, or manually select Jar Launcher from a right-click on the file, the file makes an animation like it's going to open, but nothing happens.
- Download the Forge installer for the version you need
- Install the Forge client directly into the location that Twitch expects it to be
