Create the latest install package for SEP 14.0

Good day,

I have Symantec Endpoint Protection 14.0.1904 version installed in my environment.

I need the latest version of install package for my clients.

In general, i try to generate latest package from Symantec Endpoint Protection Manager but it gives me the following - 14.0.2349 version.

I know that the latest SEP Client version is 14.2.770.

So, how to generate/create this latest edition client of SEP, please share your experience with us about this issue.

thanks in advance,
