Digitally signed driver for Vista64?

While attaching the Orangutan USB Programmer to my Vista64 for the first time, I got a message that says “This version of Windows requires digitally signed drivers” with instructions to contact the driver provider to obtain this. I already have the latest cp2012 driver but it does not have the required signature. Is such a driver available on Pololu.com? Is disabling the driver integrity check the only work-around?

Hello.

We do not have a signed driver available, and it is quite unlikely that we will ever have one, so the only option is to make your computer accept the unsigned driver. We don’t make the driver, so there isn’t much we can do to change its operation.
