try installing the cc desktop app over your current installation (assuming you have the latest 184.108.40.2066), https://creative.adobe.com/products/creative-cloud
if that fails,
uninstall everything cc including preferences, https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html
then uninstall the cc desktop app, https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html
clean your computer of cc files per http://www.adobe.com/support/contact/cscleanertool.html
restart your computer (don't skip this)
reinstall the cc desktop app, https://creative.adobe.com/products/creative-cloud.
if you're unable to install the cc desktop app at this stage, use an administrator account (solution 3 here, https://helpx.adobe.com/creative-cloud/kb/creative-cloud-missing-damaged.html)
use the desktop app to install your cc programs/trials
Thanks for the reply, I appreciate your help. Downloading the CC installation file did not work. The next day, I uninstalled the CC program from the control panel in Windows 10. It gave me the option to repair the program, which I selected. Seems to have don the trick. For two days, no AAM notification error in the Windows event logs.
For me, I get this error with Adobe Acrobat X installed. I edited the Acrobat Preferences (Ctrl+K on PC) and selected "Updater" under Categories. For "Check for updates" I selected "Do not download or install updates automatically".
