You´re using MC version 1.7.2? Use MC 1.7.10 as well as the 1.7.10 versions of all your mods. Your version was released ages agp.

Chocohead · Sep 16th 2015

If you do insist on using 1.7.2, you need the ejml library so IC2 can do the E-net maths, the crash would imply it's missing.

I downloaded the library (ejml-v0.28-libs) but where do i put it ?

Chocohead · Sep 17th 2015

Put a normal folder in the mods folder called "ic2". Then put it in there. I'm not sure how it looks for the library, but I presume as long as it's got ejml in the name it should be able to find it.

It still crashes

Why is IC2 in a zip file? You have to use the unmodified jar as downloaded from Jenkins. The error indicates META-INF being modified.

BoggyDG · Oct 28th 2015

Souldn't this be on the bug tracker?

Aroma1997 · Oct 28th 2015

No. Since it's not a bug.

GregoriusT · Oct 28th 2015

it could be a zip because SOME Browsers turn jars into zip Files.

Chocohead · Oct 28th 2015

I know Firefox likes to do it when downloading off Mediafire but I've not seen it happen from Jenkins before
