Hello,
Are you using the Latest version of CleanWipe?
I would suggest you to Either use the Latest version of CleanWipe 12.1.3001.165_RU3
OR
simply (incase of migration) migrate the SEP 11.x client to the Latest version of SEP 12.1. This would uninstall the older verison of SEP 11.x
OR
You can SEPPrep to uninstall the older version of SEP.
OR
Follow the Manual uninstall steps.
Methods for uninstalling Symantec Endpoint Protection
For this Latest version of CleanWipe Utility, I would recommend you to Create a Case with Symantec Technical Support.
