If uninstall of Endpoint Protection Small Business Agent doesn`t work via Control Panel -> Programs and Features, installation has to be removed by Symantec in-house tools like CEDAR, Norton Removal Tool or CleanWipe according to following procedure:
However when attempting to uninstall Endpoint Protection Small Business Agent using CEDAR following errors are being displayed:
"Installation cannot be started unless you solve following issue(s): Reboot your computer"
"Symantec Endpoint Protection has detected that there are pending system changes that require a reboot. Please reboot the system and rerun the installation."
Reboot of the issued machine does not resolve the issue.
CEDAR.log shows following error message:
