x21Brandon21x Posted October 21, 2015 Posted October 21, 2015 I have been using Forge 1.8 for a while with a few mods, however, I recently downloaded Applied Energistics 2. So I went and downloaded Forge 1.7.10 and when I try to run it on Minecraft I just get an error everytime. Does anyone know what I need to do? This is the error I get: [21:37:36] [main/INFO] [LaunchWrapper]: Loading tweak class name cpw.mods.fml.common.launcher.FMLTweaker [21:37:36] [main/INFO] [LaunchWrapper]: Using primary tweak class name

Choonster Posted October 21, 2015 Posted October 21, 2015 You installed a 1.8 mod on 1.7.10. Quote Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.
Choonster Posted October 22, 2015 Posted October 22, 2015 What do you mean? One of the mods you installed was made for Minecraft 1.8, but you're running 1.7.10. Mods only work on specific versions of Minecraft, you need to install ones made for the version you're running. Most mods will have the Minecraft version they're made for in the JAR's file name. The crash happened early in the loading process, so it doesn't say which mod caused it. Quote Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.
x21Brandon21x Posted October 22, 2015 Author Posted October 22, 2015 That fixed it. I thought I had the 1.7 version of NEI but I had 1.8. Thank you! Quote
