Please do not mark issues as private, unless your bug report is a security issue containing information that may compromise your server/client.

Ancient Java version, update it. This is a technical support issue; this site is for bug reports only. For technical support please use the Mojang Support Center.

Please also give the complete output of your launcher window.

Can you also upload the file "libraries/argo/argo/2.25_fixed/argo-2.25_fixed.jar" from your minecraft folder?

It ended up being corrupted install as when I started deleteing files left n right and got the uploader to install again it all worked fine.

We'll add some code in the launcher that force-verifies these files.
