Problem With drivers

[Guest Bin Power]

I'm on Windows Vista ( :unsure: ) 64-bit,

I'm trying to install the drivers given on the ZTE's website, but they won't install saying:

The folder you specified doesn't contain a compatible software driver for device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems.

My phone is no longer recognising the PC and the PC is semi recognising my Orange San Francisico

HELP!
