I cannot delete *.dmp file from SEP folder log.

I am facing some issue with multiple client, include my server ( Windows 2012 R2 ) that already upgrade version from 12.1.5337.5000.105 to 14.0.3897.1101.105.

I cannot delete all log ( .dmp files ) in C:\ProgramData\Symantec\Symantec Endpoint Protection\12.1.5337.5000.105\Data\Install\Logs\ *.dmp , Taking more that 60 GB from my C drive.

because this server already running SEP version 14.

Please advise.

This is the folder that take 60GB on my C drive.
