It never appeared in the Windows 10 list of applications, nor in the older Windows app to remove applications, nor did it appear in CC's list of applications.
I finally saw a suggestion to use File Explorer to find the uninstall routine listed in the program files directory.
All done!
How can I uninstall this program...
Windows 10 does not include it on a list of installed programs, but the program is installed and runs on my computer.
