OK i understand. You have it a bit off though. DarqUI_Notify is there to just tell you when you need updates, or as a URL Helper. It is completely separate to DarqUI_Unified.exe. Simply run the DarqUI_Unified.exe app and you will get a UI that comes up that looks like this:
You can setup / install / use the UI from here. If you go under Settings on the left hand side there are 2 options to make the Unified app itself auto check for updates where you can just click install in the app too. That can be done like this:
As far as "notification popup" i'm still not sure what you mean by this. Do you mean that this app won't load:
or do you mean when you right click the program in your system tray it won't show the options? Like below?
