setup second life corrompu :(

bonjour a tous,
lorsque j'essaye de telecharger le setup de second life
en plein milieu du telechargement il me dit :

la fenetre du telechargement de second life a dit:

NSIS Error
the installer you are trying to use is corrupted or incomplete.
this could be the result of a damaged disk, a failed dowload or a virus.

you may want to contact the author of this installer to obtain a new copy.

it may be possible to skip this check using the /NCRC command line switch
(NOT RECOMMENDED)

je l'ai telecharger a partir du site officiel de second life

help please

merci a tous
A+
[ps: voilà le nom du setup : Second Life 1-18-0-129 Voice First Look Setup.exe]
