Error message refers to non-existent right-click menu

[Smylers]

The update notification icon is showing me the attached error message, which asks me to “run Package Manager from the right-click menu”. But since switching to Unity, there isn't a distinct right-click menu; whether left- or right-clicking the same menu is displayed. And none of the available menu entries are labelled ‘Package Manager’.

Please can you update this error message to reflect these changes. Thanks.
