I have read through the EAQ and pray I have a candidate here of a bug. I am using the regular launcher, and only 1 mod: millenaire. I have the new MC 1.4.2, using the latest forge (601350), and no beans. I have also tried starting MC with forge alone (no mods), and same result. Below is the last bit of the log which shows the errors. The EAQ had some of the same code (for example: java.lang.NoClassDefFoundError), but not ':AUX' written after it.

I hope my error is a simple fix. Thank you in advance for the help.

Have you tried installing Forge a using different method? (i.e. using a launcher)

Use a different instillation procedure, I advise 7zip, whatever you did made the aux class dissapear, which probably means you tried extracting the entirity of minecraft.jar, you can't have a file named aux on your computer, so, you need to do it in memory. Either use a launcher {multimc} or do it properly using a archive manager {7zip}

I'll add it to the EAQ.

Problem solved! I used 7z, opened both the forge zip and the minecraft.jar, selected all the files in the forge zip and dragged them over to the minecraft.jar 7z window. After copy, I tested the archive. And voila!

 

For the record, I was doing exactly what you described: completely unzipping minecraft.jar, moving the files over, and then rezipping (and renaming back to .jar)

 

Thanks!
