OpenCL 1.1 on Quadro Hardware

Has anyone managed to get OpenCL 1.1 working on Quadro hardware (Quadro 4000, Quadro 2000 or Quadro 600)?
I’m using the OpenCL 1.1 Conformance Candidate (devdriver_3.1_winvista-win7_64_258.19_opencl1.1.exe) but it won’t install on any of the above hardware reporting that no suitable hardware is installed in the PC.
I on Windows 7 x64


Quadro FX 1800
Win XP x64

Everything works fine.
