manually uninstall symantec endpoint protection 12.1.2015.2015

Hi!

I am installing SCEP to my serveres. I have send SECP from SCCM as the SCEP automatically uninstall sep and at the same time SCEP will be installed to these servres. 90% of serveres have got scep without any problem, and sep has been removed automatically, but 10% of servers have beed failed under the installation.

I tried to remove the sep from control panel but that is not possible .Is it any cleanwipe tools avaiable? or any good idea to remove the sep 12.1 from those serveres. I don't want to go the registry and remove from there,

Regards

KSU
