mod_IC2AdvancedMachines : Unsupported major.minor version 51.0

[havocx42]

It looks like the Tekkit 2.1 server is currently not compatible with the recommended version of java and requires Java 1.7

Update to Java 1.7 to fix this problem. Hopefully.

Java 1.7 can be found here. I'm not providing support for installing Java. I'm afraid you will have to figure that bit out yourself.

Also please ensure that if you have a 64bit OS you are using the 64 bit version of java.

Thanks to tradari for pointing this out.

I've updated to Java 1.7 using the Windows x86 download (I'm running Vista on a 64-bit, I assumed this was the correct installation as when I install programs, they go to Program Filesx86), but when launching the server, I still get this error:

http://pastebin.com/29vyPW1j

the program files (x86) exists on all os weather there 23, 64, or 86. this doesn't determine your os bit. if you are running vista on 64 bit, then get 64 bit download.

What has this got to do with "Unsupported major.minor version 51.0"?

No, no he can't. I've locked the thread. And you...need to go post a bug report.

*Edit: I unlocked the thread just in case, after I realized that the 2nd threadjacking with no bug report today caused him to be banned. Oops.

If You Didn't know There's A simpler way. I just messed with the bat file. This works for me.

java -Xmx1024M -Xms1024M -jar Tekkit.jar nogui.

wheres the pause when i put that in it doesn't work the window pops up and then disappears in a split second unless i put pause
