Policy does not work

I manage Symantec Endpoint 12.1.6 mr2 with SEPM.

Computer are Windows 7, Windows 8 and some windows 10 in a domain.

Users have not administrator rights.

I 'm doing the next:

 I  disabled Lotus Notes scanner in policy in SEPM and it had deployed to computers with success.

Now I have enabled Lotus Notes scanner in policy in SEPM but in computers shows that "Lotus Notes scanner" is disabled and shows a message warning.

I have forced in client to download changes of server but It does not change.

I think that exists some problem with deployment and application policy.

The only solution I find, is to remove and install again Symantec Endpoint in the client.

Please, could you help me that solve it without I have to reinstall software again?

Thank you
