Symantec EndPoint Protection (Small Business)

Hi,

I have a Symantec EndPoint Protection (Small Business) 12.0.1001.95 on a server.

I have Windows 7 clients who are installing the Endpoint Protection client 12.0.1001.95 successfully. I have now new windows 8.1 clients and I think that they are not compatible with symantec endpoint protection 12.0.1001.95.

Am I right or do I have to install the Symantec_Endpoint_Protection_SBE_12.1.4 on the server to make Windows 8.1 clients work?

Thanks & Regards.
