Unable to add packages to SEPM

I am trying to add client install packages to the SEPM.  It will only accept .zip or .info files.  I have downloaded the .zip (Symantec_Endpoint_Protection_14.0.0_MP2_All_Clients_EN.zip).  It will accept that as a file, then error out with "Failed to retrieve the build number of the package for the package list generation."

I see a previous thread from January with this issue: https://forum.support.veritas.com/connect/forums/unable-add-client-install-packages

That thread provides a link to manual import steps, which specify using a .info file that is not present in the .zip file I have.  Do I have the wrong file?  If so, where can I get the correct file?  This is the only download I could fine under my account.

Thanks.
