I love to determine if there's in whatever way to understand if your wordpress plugin is simply installed. I do not care if that's triggered yet, but only when that wordpress plugin is installed !

Are you aware worthwhile method of doing that?

I must become more specific. I understand how to locate the plug ins and I understand how I can tell if you will find installed. Now you ask ,, if there's any programaticly way to see if the wordpress plugin is installed.

ie: WordPress give to us register_activation_hook() to create any operation we love to around the wordpress plugin activation, but there's no any relevant hook for wordpress plugin installation. Can there be in whatever way to look for the wordpress plugin installation ?

If you're able to view it within the listing of plug ins underneath the Plug ins-page in your soul admin-system, then your wordpress plugin ought to be installed.
