I'm getting the exact same problem, i believe its something to do with different versions of java conflicting with each other, but i have no idea how to fix it...

[alias180]

I have exactly the same problem. So annoying! But I think this is a launcher bug not a tekkit classic bug, and you might have seen the post about not mixing the two up. You may want to consider relocating this to the launcher bugs section so it gets more attention and you don't risk a ban?

Personally I am dying to see the issue solved. (I'd just like to say that this only happened to me after I messed about trying to create a server. When it didn't work I gave up and for some reason reinstalled the launcher. Not sure if it's related?)

[alias180]

And yeah, help would be appreciated :s

Last time I saw an unsupported major.minor error, it was because someone's Java was outdated. Upgrade to Java 7, Classic contains at least one mod which requires it, I can't remember which.

[alias180]

Ah! Thanks very much! Any idea why it is only Tekkit Classic that won't work?

[theprolo]

Like I said, one of the mods is incompatible with Java 6. I think the incompatibility was fixed in later versions, but Classic doesn't have access to them. Either that, or the mod was removed.

[alias180]

IT WORKED!!! THANK YOU!!! And, oh, okay thanks

[Handyo]

@alias180 - are you using mac also?? if so ill give the Java 7 a go and hopefully it will work.

[theprolo]

Whether you're using Mac or not, updating to Java 7 should fix it.

[Handyo]

YES!! Thank you for your help!

[alias180]

Yeah I'm on mac

[Handyo]

annnndddd..... its back with the same error, with my java fully updated :(

[theprolo]

You sure it's java 7? Give me a log, it might help clear things up.

I remember cases of Minecraft still using Java 6 even if Java 7 is installed.
