Issue

Can not get FTB Evolution to start, keeps saying missing jar. I tried to change my java version, I run this modpack thru CMD right now, was running java 8 now 26. I tried to start a new instance, I have tried to put modpack download in augments.

Reproduction Steps

  • Downloaded Java 26
  • updated instance
  • tried different instance since first one was using java 8
