What's your technic to identify a new installation of your plugins?
I could go with a pref setting. If it is not set, mean that it's a new computer. But for all the old one, it will not work.
is there any sdk function provided?
I'd like to launch a welcome popup when user install my plugin as a lot of them are installing it but probably don't really understand everything and never use it. So I'd like to launch a popup with an helper for the first install.

I may have misunderstood you, but why not have a preferences field "displayedPopup". If it's true, that means the popup has been displayed already (and thus won't be displayed again).
Because, I have current user and I don't want to show them the popup..
But, I found a way and do a call to my server. I'll change to do directly with a pref.showpopup when my current users will all have updated this value.
