Indefinite "wait" state installing HP connectivity kit

[rkf]

Hi there,

after aquiring a HP Prime G2 as an addition to the Rev C version in my collection I tried to update the firmware, which prior demanded an update of the HP connectivity kit - a task I did numerous times before.

But now I'm stuck indefinitely on "Please wait while Windows configures Hp Connectivity Kit (64 bit)". I tried uninstalling previous version, I tried both 32 bit and 64 bit versions, I tried .exe and .msi installers to no avail. Antivirus software is disabled already to exclude also that as a reason. BTW, I have a Win 10 Enterprise 2016 LTSB version installed.

Any ideas out there, google wasn't of any help with this?
