Installation de jeux

Bonjour,
je veut installer mon jeux football manager 2011 et il me mais une erreur c'est produite :

Archive: /media/FM2011/autorun.exe
/media/FM2011/autorun.exe
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
note: /media/FM2011/autorun.exe may be a plain executable, not an archive
zipinfo: cannot find zipfile directory in one of /media/FM2011/autorun.exe or
/media/FM2011/autorun.exe.zip, and cannot find /media/FM2011/autorun.exe.ZIP, period.

merci
