We have done some test with Vista - all of our current products work fine
See the current table here:

Older software such as MillCAM designer which was written around the time of Windows 95, will not install - we didn't spend much time trying to get the old things working, so there may be a few tips and tricks to getting 16 bit applications to run.
If anyone has got old Denford (or related) software working on Vista then let us know how you got on.
