Hi there,

I am trying to connect conn4x to my hp 50g on Windows 10 64 bit. I downloaded the USB drivers install program from Hpcalc.org, but the install fails because the 64 bit driver is unsigned.

I read an earlier thread from 2015 regarding this problem. One member downloaded updated drivers from HP's site. Unfortunately, the link referenced in that thread for the new USB drivers no longer works. It seems hp support no longer has links to any of the calculators that HP is not currently selling.

Can anyone knowing where I can download these updated driver point it out to me so that I can connect my calculator to Windows 10?
