HP Prime Connectivity Software does not install on Mac OS Catalina 10.15.3

HP Recommended
HP Prime
macOS 10.15 Catalina

I dusted off my old HP Prime and would like to update the firmware. I am getting an error message when I attempt to install the HP Connectivity app. When is the version of this app that properly supports the current Mac OS going to be available? Here are some details:


Download HP_Prime_Connectivity_Kit_20200116.dmg dated 1/23/2020 from (also tried the standard firmware link on the support web site.

Drag application into the Applications folder.

Error dialog pops up:  "HP Connectivity" can't be opened bacause Apple cannot check it for malicious software. This software needs to be updated. Contact the developer for more information


The system is a MacBook Pro (16-inch, 2019). The operating system is macOS Catalina version 10.15.3.
