My passport 250 sous linux

Bonjour, le papa noel vient de m'offrir un disque dur externe my passport essential 250gb/go. Je suis sous linux et voici le message d'erreur lorsque j'essaie de l'installer:
Archive: /media/WD SmartWare/WD SmartWare/dotnetfx.exe
SmartWare/WD SmartWare/dotnetfx.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/WD SmartWare/WD SmartWare/dotnetfx.exe may be a plain executable, not an archive
zipinfo: cannot find zipfile directory in one of /media/WD SmartWare/WD SmartWare/dotnetfx.exe or
/media/WD SmartWare/WD SmartWare/dotnetfx.exe.zip, and cannot find /media/WD SmartWare/WD SmartWare/dotnetfx.exe.ZIP, period.
Qui pourrait m'aider? Merci
