Thanks for your interest, guys.
Maybe we are getting somewhere.
In HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins
I do not have the reference to FlashPlayer.
Is that surprising given the following registry entry for FlashPlayer:
Key Name: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Macromedia\FlashPlayerPlugin
Class Name: <NO CLASS>
