HP Solution Center not working - Alternative way to start HP CUE-Scanning Flow Component

[jp_Oz]

Like most others, I have tried several solutions from the forum now that Flash has been disabled and killed the HP Solution Center, but Hp Smart cannot find my USB connected device, and HP Scan and Capture does not offer OCR, which I need. I have used up lots of time installing/uninstalling/reinstalling the above components to no avail, and am reluctant to use up even more time on them. The OCR provided with the original drivers is better than other printer/scanner devices I have used and I would like to get that functionality back.

I have found a very clunky work around by using HPPSdr.exe, which is HP's printer and scanner doctor. This finds my device and starts the HP CUE-Scanning Flow Component (hpqkygrp.exe) correctly, provides the normal scanning options dialogue and performs scans as if it was directed by the defunct HP Solution Center, reporting no errors. This gives me back the functionality I need, but is somewhat time consuming each time I use it.

If I try to start this component (hpqkygrp.exe) directly from File Explorer or a shortcut, it pops up an error "The scanning software was launched with improper command-line arguments" and extended info "8[(-1, 0, 0)].

My BIG question is:
How is the printer and scanner doctor (HPPSdr.exe) calling the HP CUE-Scanning Flow Component (hpqkygrp.exe) without triggering the error message? It seems to me that it must use the correct command-line arguments to succeed, sooooo - does anyone know what the required command-line arguments are? And if so, could they please post them for us to use?

Thank you for any assistance you may offer.
