Modpacks won't launch

Funxional6 · January 1, 2016

After I updated my Java to 1.8_66, the whole Technic launcher started doing it's own stuff. When I launch a modpack, it starts loading, but when it should start, it just dissappears and the launcher comes back.

You can run java 7 alongside java 8, I do it myself, try specefying the amount of RAM java can use and the version on the technic launcher

I installed java 1.7.0_79 and used it, added RAM usage to 2MB, but it still doesn't work. Any other ideas?

This error is reported when the org.slf4j.impl.StaticLoggerBinder class could not be loaded into memory. This happens when no appropriate SLF4J binding could be found on the class path. Placing one (and only one) ofslf4j-nop.jar, slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar on the class path should solve the problem.

You can download SLF4J bindings from the project download page.

Your issue is you have this going on. [B#339] Picked up _JAVA_OPTIONS: -Xmx256M. That's limiting anything java related to 256MB of ram max. If you can clear them on your own then you'll be good to go, if you don't know how either use google or come to the technic discord help channel

Jumpandshootbeef, I have absolutely no idea what you were talking about, maybe you could show me a video or something. I won't be able to do that method on my own

Zaza7, I checked the Java runtime environment settings, there were no runtime parameters set.

Do you know how to mod a jar file? @Funxional6 ?

If you mean putting mod files in to the original minecraft.jar file then yes.

You need to put any of these .jar files into the modpack.jar, or fetch yourself the latest mc forge universal, I hope that fixes it

First I put one of those .jar's in the modpack.jar file, it didn't work. Next I put almost everything in the SLF4J file inside the modpack.jar, still didn't work. What to do next.

Well I've found out that that error doesn't have any significance. There is another error causing this. The error we have been discussing happens every time. Please turn on console, launch the pack and give the error code.

I know this bug:

Search around for references to _JAVA_OPTIONS since there is some Windows program (as I understand it) which sets that global environment variable and you need to remove that if you want to use something other than 512M in Minecraft.

It seems that a program you have automatically sets your java settings too low, you need to find this

I found a way to fix the "Picked up _JAVA_OPTIONS: -Xmx256M" bug, just remember to restart your computer after doing that, otherwise it won't work.
