Does that *exact same* executable work in Windows? Could the download have corrupted it? A simple google query shows up similar questions. For instance: http://www.emailquestions.com/help-desk/995-do-i-fix-7-zip-error.html (proposes a simple solution) or http://forums.nvidia.com/index.php?showtopic=103043 It might or might not be a Wine bug, but you should be able to get away with it by manually extracting the file with a file extractor and 7-zip support. nevertheless, that console log would be helpful if this doesn't work. Also, if it does work, try it out in a Windows machine to see if it's a Wine bug, please. Cheers, Jorl17
