I have problem with CASE statement, it doesn't work. I also need to use connectivity kit but I tried some old versions that they don't recognize the calculator when it is connected. Any solutions?

I'm pretty sure the Oct 30 2013 version (release 19148) is the latest.

I installed the connectivity kit from 2013-11-11 and the virtual calculator from 2013-11-10, which are both on HP's FTP site: ftp://ftp.hp.com/pub/calculators/39gII/.

The calculator should appear as a "HID-compliant vendor-defined device" in Windows 10 and doesn't use any special drivers, only standard Microsoft drivers. If it shows as a USB device with an exclamation mark in Windows Device Manager, try deleting the device in Device Manager and rescanning.
