My passport not recognized by windows 7 vaio (64 bits)

Hello everyone

after installing the driver WD SES Driver Setup (x64) , MY PASSEPORT drive is still not recognized by Windows 7. The small indicator light, but the drive do not appear in the disk manager. I know he normally works because I can use it on another computer with Windows Vista. 

I’m stuck and I did not want to throw in the trash MY PASSEPORT.

Who can help me ?
