Endpoint Protection

I'm encountering an issue when trying to install SEP 12.1 RU2. Below is a screen shot of the error message and here is the actual text.

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.

Now, the error message is pretty straight forward, but that certificate isn't installed on any other machines in which SEP installed correctly.

Any thoughts???

SEP 12.1.2 is old! Do not move to this version. Get to 12.1.5

@Kenneth, why are you suggesting this?

If you are planning to upgrade or migrate to Symantec Endpoint Protection 12.1.5, please take a look at the latest how-to article created by our very own SEP content council team.

I am sorry. 12.1.5 is what I meant. It's the same technote link anyway. I have edited and corrected the version on my reply. Thanks for letting me know!
