I uhh.. found the password to ALL zip archives of Lunia..
I opened up Lunia.exe in PE Explorer and browsed around until I found something about opening zip and inputting passwords.. somewhere there I found a name, and I thought: "let's try to put that in, although I can't believe that's it"
And whaddaya know? It was the password
Did I just do a bad thing? Do you guys want to know the password?
