I have Win 7 on my desktop, but run AHP on my notebook (so I can bring it to the CM15A in the breakfast nook
). So, I haven't had to attempt to install AHP on my desktop yet.
However, if one has Win 7 Professional or Ultimate, there is the new Virtual XP capabilities. Within that, one can install any XP program and USB driver. Therefore, if nothing else works, one should be able to install AHP and the CM15A drivers that way.
I have already installed two old, no longer supported, USB devices and their software this way, and it works amazingly.
