The policy notification in Computer Homepage tab is wrongly showing violation because in
the Software tab indicates correctly the updated 14.5 agent is installed.
CA Client Automation - All versions
This might due to an old violation when the agent was still in old version before the upgrade to 14.5.
Click on the Violated Policy -> 'CA Agent old version Installation' and try to remove it from
the list.
Or, navigate in the DSM Explorer Tree to the Policys and find that policy to reset.
After that, righ-click on that policy and Evaluate to see if it will reapper.
