9you Audition Online Installation Help

I need help installing 9you's Audition Online. I'm okay with everything up to the file extraction. At the end of the extraction, a pop-up message that states: "Windows cannot find '???6.5setup.exe'. Make sure you typed the name correctly, and then try again".
The Season 6.5 folder is there on my desktop. and so is everything that's supposed to be in there. But when I open the setup file, a message pops up and says that setup.exe is not working.
Can anyone help me?
