Update firmware: 20170710 will not install

[acapde]

Hi,

I got an HP Prime calculator for Christmas (I guess I was in the “nice list” by mistake).
The calculator came with software version 2016 04 06 (10024) so I decided to upgrade. I installed the connectivity kit (build: 2016 12 8 Rev:11226) on a Windows 10 (64-bit) laptop, as soon as I launched it downloaded FW version 20170710, so far so good.

Now, when I try to update the calculator, the progress bar on the computer disappears when it reaches 43%, the progress bar on the calculator remains there but not moving and nothing happens. I’ve tried different computers (Win 7 & Win 10, always 64 bits, USB 2 and USB 3 ports), I’ve even tried older FW packages but the calculator never gets the new firmware. I also tried a factory reset (format disk C).

I would think that what I’m doing is fairly simple, I upgrade gadgets all the time (part of modern life), am I missing something here? Is there a special song I have to play while doing this?

Any suggestion will be much appreciated.

Thank you.

Andres.-
