i'm kinda rusty 'cause i can't install linux on my new mobo, but have you tried
sh Audiocoin-qt-ubuntu?
Ok, thank, I did tried sh Audiocoin-qt-ubuntu and the shell told me:
Audiocoin-qt-ubuntu: 2: Audiocoin-qt-ubuntu: Syntax error: ")" unexpected
typo?
?

Sorry I am not know it that you told
hopefully, someone with more linux experience can help, but for what it's worth, the response you had from the terminal:
Audiocoin-qt-ubuntu: 2: Audiocoin-qt-ubuntu: Syntax error: ")" unexpected
would indicate that a ")" was in the comandline that preceded the result, but shouldn't have been there
maybe try again and post the output here?
