Symantec Endpoint Protection disabled on startup

After installing 12.1.2 64 bit client of Symantec Endpoint Encryption I now have to manually enable the software each time I restart or boot up my laptop.  There doesn't appear to be any error logs and the policy hasn't changed, all I did was install 12.1.2 exe over the existing 12.1.1 client.  The previous client worked without interaction.

Many thanks for any help provided.
