Error 25010 - SEP 12 RU 2

Good day,

I get this error when I try to install SEP 12 RU2 on one of my servers?

Product: Symantec Endpoint Protection -- Error 25010. Could not locate "Microsoft Test Root Authority" certificate in "Trusted Root Certification Authorities" store. It is required for this build of Symantec Endpoint Protection. Please install it and retry Symantec Endpoint Protection installation.

Any ideas on how to troubleshoot this
