Walter:
[thanks for the reply]

The SetpDiOpenDevRegKey is for 2k and beyond, how about 9x systems?

I am trying to use VS_FIXEDFILEINFO, to obtain the date, though I have
fear that it may return the time stamp, which I don't want, I want to
date given by the vendor. But before I get there, it gives me 0 for
fileVersion->dwFileDateMS
fileVersion->dwFileDateLS, any thoughts?
