Probleme installation eclipse sous vista

Bonjour,

Je n'arrive pas à installer eclipse.
J'ai telechargé le dossier zippé:
- eclipse-java-ganymede-SR1-win32
Je l'ai dezippé dans C:\Users\nomUser\Downloads
Message d'erreur :
"An error has occured. See the log file C:\Users\nomUser\Downloads\eclipse-java-ganymede-SR1-win32\eclipse\configuration\1225736293768.log"

J'ai donc essayé de le dezippé dans : C:\eclipse
message d'erreur :
The Eclipse executable launcher was unable to locate its companion shared library


De plus a chaque fois que j'ai dezippé (avec "extraire de windows" et avec winzip) il y a eu une erreur "l'explorateur windows s'est arreté

Je ne sais plus quoi faire
Ai-je le bon eclipse pour java et vista ?
Que dois-je faire d'autre ?
