The instructions on that first page indicate I should use Control Panel > Programs and Features, but that is not possible since none of these programs appear in the listing.
I did not mention that earlier I was reading the forums looking for answers and encountered this cleaner, AdobeCreativeCloudCleanerTool.exe, which I installed and ran. A rather archaic looking DOS command window tool. However, it did not resolve, remove or accomplish anything but consume time. I will give the CloudCleanertool another shot and see if anything shows up in the log to explain itself.
Ok, I have revisited the help pages called out and have run the AdobeCreativeCloudCleanerTool.exe numerous times with a limited change. The list of programs the tool shows has gotten considerably smaller, and I have rebooted, yet many CC applications are still present in my Start>All Programs, and on disk in Program Files. Looking in the log file is now a little overwhelming as it is accumulative of each time I tried to run the tool. However, there are warnings about not being able to remove folders, and about not being able to locate Registry entries to try and remove them as well.
RoboHelp 11 is still on disk but no evident way to UNinstall it. It is not part of CC so I figure the cleaner tool isn't even looking for it. It is not in Control Panel.
It does look like Captivate 8 was 'mostly' removed. All that's left behind is empty folders, the Quiz Analyzer, and the Adobe Patch directory has over a GB of folders in it.
1) Cleaner Tool no longer sees the installed products
2) CC programs are listed in Start
3) RoboHelp Trial is still in Start with no apparent way to uninstall it
