How to know when vb4 Plugins have updates available?

In my vBulletin 4 control panel as admin, under Plugins & Products -> Plugin Manager, I see each installed plugin, whether it is Active, and links to Edit or Delete. Within the Edit page for each plugin, I see options specific to the plugin; but neither on the Plugin Manager page nor on the specific pages for each plugin do I see a Mark as Installed option...

Similarly, on the Manage Products screen, I see a list of installed products e.g. vB Bad Behavior (vB4) and Spam Hammer, and an Edit link, but no Mark as Installed option.

I'm sure I'm going to end up feeling silly, but ... Where is the "Mark as installed" option for Products and Plugins? (or, are "mods" different from "products" different from "plugins"? I'm looking at Products and at Plugins).

Thanks,
