Windows Vista 64-bit is slightly different from the 32-bit version as it requires digitally signed drivers. The problem with that is that Microsoft charges developers money for the driver verifications, and far from all developers feel it’s worth the effort to submit every driver and application to have them signed by Microsoft. NGOHQ has released a tool that enables users to bypass the verifications process, which in turn lets you load unsigned drivers. We haven’t tested this, and we urge you to be careful, but if you want to try it out you can download the tool from NGOHQ’s website.
