Just updated our vSphere appliance to 6.5.0 Build 15259038.
One of the reasons for this upgrade was to bring Update Manager into the HTML5 view rather than the Flash view. The upgrade went fine, I can see the update manager plug-in is enabled in the flash client as you cant see plugins in the html client.
But on the html client still not seeing update manager. I created a new local admin user to test and does not shop up for them so assuming its not a permissions issue, I have restarted the services and the VSCA server to no avail.
Does anyone know how to resolve this?
