Operating System: W7 64x Ultimate Edition

Antivirus Program: BitDefender
Description of Problem:
So I'm trying to install the launcher for my brother, and when we finally get it to open (just hangs at the loading screen, we used a different java file to open it) he gets the launcher version 126.96.36.199. He can select modpacks to use (only tekkit, tekkitlite, and a few others, but no bigdig which he was going to play) but when he tries to dl them he gets an error, saying its failed to update. I've given him my whole tekkit folder (illegal? i dunno, he has a minecraft account too) and tried deleting his .tekkit and .tekkitlauncher folder. I think he backed up an old tekkit version when he reformatted and his computer is trying to launch that or something, but I couldn't find it anywhere at all. I've updated his java to 7u45. I've made a new user account to try and see if his account is just bugged, still got the same launcher. Not sure what to do.
We are using the most up to date launcher, downloaded right off the site. But it just hangs at the loading screen even after I delete those folders. It hangs at the same user file
Don't have access to it atm, but it barely starts and it hangs on "unable to load users.yml" or something like that.
