USB, Windows Server 2008, FXT009

When I install AirPrime - USB driver for Windows 7 & 8.1 (SL6087, Q26 series, WMP series).
And trying to open usb driver configuration windows server gives me this error: “there is no driver installed on the system”.
What could be wrong? Where could I find drivers for windows server?
I am using FXT-009

So I presume you used this to install them?

I have also checked the problem reporting database and it appears that our drivers do not support Win server 2008, that was for version 3.8.6 but I cannot see any reason for this to have changed.
