Intuilink_VNA with Windows 7 64 bits

I'm facing heavy problems to communicate with my Vector Network Analyzer 8720ES.

Im using Windows 7 64 bits, and I installed both Agilent IO Libraries Suite (version 16.1.14931.0) and Intuilink_VNA 1.3 (installing file version :

The IO libraries SUite works perfectly and recognizes the VNA trough the GPIB/USB connection. I can also communicate basically with VISA commands (Interactive IO).
But the true problem is that Intuilink doesn't detect ANY connection by GPIB/USB. When I launch the Excel - or Word - add-in, and click on "Connect to VNA", I don't obtain any adresses... and same for any software of Intuilink_VNA.

I precise I installed Intuilink_VNA with the compatibilité mode "Windows XP - SP3". I had already done this installation on a previous laptop with Win 7 32 bits/Office 2007, it was working perfectly, but the laptop hardware recently crashed. =S

Do you think it's due to my 64 bits OS ? Does a solution exist ? I really need your help, thanks in advance for any answer.
