Hello, I recently installed the Modpack Launcher "Void launcher" from http://voidswrath.com/newwp/ and I can start up the launcher just fine, but every time I try to start the modpacks, none of them will open. Here is an example from the version 1.6.4 modpack "Fellowship," when I try to open it the console says this:

I don't know what it means, other than that it is a problem with forge. I would really appreciate if someone would help me resolve this issue

Either get the legacy java fixer mod and add it to the mod pack or get Java 7 and remove Java 8

Even if I have windows 8?

Operating system has nothing to do with forge version compatibility with specific java versions.

Thank you! Installing java 7 and uninstalling java 8 did the trick, the mod packs run perfectly now.
