Attempting to remove Symantec Endpoint Protection Manager (SEPM) 12.1 RU4a using the CleanWipe tool distributed with Symantec Endpoint Protection (SEP) 12.1 RU4 fails.
The version of CleanWipe released with SEP 12.1 RU4 was released prior to the creation of SEPM 12.1 RU4a. The 12.1 RU4 version of CleanWipe is not programmed to handle SEPM 12.1 RU4a.
To remove the SEPM use the Windows Installer. If the Windows Installer is unable to successfully remove the SEPM contact Symantec support for assistance.
