Prerequisite JRE not being installed

Prerequisite JRE_SE 1.8.0_162 (x86) not being installed (OR NOT FOUND?)

Added the prerequisite to my project with option "Install before feature selection"

Then build install.exe and run it on a Windows 10 Version 20H2 machine with setup /debuglog

This is the sniplet of my Installshield.log:

It looks like the install is detecting the prerequisite has already been installed based on the log.
If you have been using this machine for testing its possible that a previous installation and subsequent uninstall is not fully complete and requires a reboot.

Try rebooting the machine and running the install again to see if it will detect the prerequisite then.

I have given it another try: uninstall - reboot - install,  but no change, log entries are identically
