can not open Epson Scan 2.pkg driver software running OS X 10.15.1

I can not open Epson Scan 2.pkg driver software (nor Epson Scanner ICA Driver.pkg) running OS X 10.15.1. Even when selecting "Open with Installer app (default)" from right click pull down menu. Nothing happens, no error message, no system message. Trying to install for Epson V-550 scanner. I have Epson Software Updater.app 2.4.1 installed, and it seems to be running ok. But when I open it, it wants to update the Updater. I ok that, but the install fails and I get "Install failed, Reboot the OS X and try again." did that but no change. Couldn't find new Updater on Epson website to download. Just updated to Catalina yesterday. Am i missing some security aspect of OS X that is preventing the .pkg s from opening? On Epson's site for scanner I see following "Please note, at this time, the drivers for Mac OS 10.15.x do not support the Digital ICE functions of the V550 or V600 scanners." I took this to mean software might not provide all the abilities of scanner, but is this why .pkg software won't even open?

JUST found Epson updater v 2.3.3 to download, will try process again. Tried, same issue, Updater.pkg won't open at all.
