Try this:
- Download the wanted firmware file (.zip), e.g. HP_Prime_Calculator_Firmware_20200116.zip
- Unpack the zip file
- navigate in explorer to
C:\Users\<YOUR_NAME>\Documents\HP Connectivity Kit\Firmware\PrimeG1
- copy the contents of the zip file to this location
Then connect your prime to the PC, and start the Connectivity Kit.

Thanks Thomas,
I have done everything you describe, but the problem is that the firmware loaded in the Prime is the newest version 2021-05-05 and I always get the message "No updates available", because the version 2020-01-16 is older. I would need to format the C drive to delete the installed firmware. But I do not know, how to do it and how to backup my files, because HP ConnKit lost this functionality.
Once more thanks
Slavomir
