Connectivity Kit

To summarize first:
- my HP Prime has sw version 2.1.14588 (2021 05 05), hw version C, serial #3CD6200039, os: V0.050.640
- PC: Win version 21H1 (Build 19043.1110)
- HP Connectivity kit x64_20210609.msi, version 2.1.14592
-----
Connectivity kit starts well. Name of my HP Prime appears in a pane. When clicking the HP Prime name, list of installed application appears, but quickly disappears without possibility to click on any application. HP Prime simultaneously restarts and X2+y2=1 appears on the calculator screen.
I am an old guy (81) and I use my calculator more for fun, than for serious calculations.
Very previous versions of the connectivity kit worked ok.
Any help will be appreciated.
Thanks
Slavomir

RE: Connectivity Kit
Not a Connectivity Kit user myself, just my experience with USB in general is that trying another computer/port/cable is a worthy exercise. Especially cables are prone to malfunctioning. Sorry if I'm just stating the obvious...

RE: Connectivity Kit
Especially now that they have the USB-Charging-Only abominations.

RE: Connectivity Kit
I had the same issue and after an installation of the CK on an other computer I got the same problem.
I did indeed a factory reset and now it's OK.
Here is the procedure I followed ( I don't remember where I got it) :

"The following always resets the calculator to factory-new condition:
• Press and hold c, f, and o
• While holding them all down, poke a paperclip into the RESET hole in the back.
• When the diagnostic screen appears, release the c, f, and o keys.
• Press 4 (FLS Utility), then 3 (Format Disk C), then Enter. This will wipe the memory of the calculator to factory-new condition.
• When the blue OK appears, press Esc, then 9 (RESET).
• It usually ends with the initial setup, including swiping the tiny HP logo to the right with your finger, selecting the default language, and/or other stuff, depending on your hardware and firmware versions."
Hope it will resolve your trouble.

RE: Connectivity Kit
I had the same issue. This has working for me with my HP Prime rev.A G1 without data lost:
Uninstall the current CK.
Install the CK version v.2.1.14425 (2020 1 16).
Copy v.2.1.14425 (2020 01 16) firmware files to 'Documents/HP Connectivity Kit/Firmware/PrimeG1/'.
Launch the CK and upgrade (downgrade) the HP Prime to 2.1.14425 (2020 01 16)
Now you can do a backup of your calculator (in a ZIP file) with the CK.
Uninstall the CK v.2.1.14425 and install the lastest version.
Clear the HP Prime memory with ON + APP + Esc keys.
Upgrade the HP Prime to the lastest version.
To restore some of your applications, unzip the backup file, drag & drop the folder ending with ".hpappdir" to 'Application Library' in the CK application.
