Check the return value from the silent uninstallation command. If necessary, check the uninstall log file. However, if the return value from the silent uninstallation command is 3 or 9, no uninstall log file is created. For details, refer to "E.4 Return Values for Silent Uninstallation (for ETERNUS SF Manager, AdvancedCopy Manager CCM)".
The uninstallation result can be viewed in the uninstall log file, too.
Open the uninstall log file to see "ResultCode" in the ResponseResult section. In "ResultCode" is written the return value from the silent uninstallation command.
