The best one is to run service which will give you an oportunity to run different process on demand. But of course at first you must have Admin Rights to install and run such service.

It is an options, but it will be fired at time, and not at demand.

This is the normal Windows security behavior, when accessing the GUI using functions like: WinActivate("New Proprietary Program") MouseClick("left,xpos,ypos) Meaning, The controlled program and the controlling/automating program must have the same security level for the controlling/automating program to be able to access the controlled program. In your case Lower the security level/runtime environment of the controlled program. or Raise this level for the control/automation program. In your case as you showed to us, the #RequireAdmin did the trick

With PDF I was just curious because I came across it while searching for solutions to other problems. With JSON I just wanted confirmation. By asking this directly, it will be easier for everyone to find it in search engines, even for me in the future when I need it. Now I'm focusing on WebView2 Anyway, Thanks for yours answer. mLipok

oh... Nice Thanks So we can use this also for: https://learn.microsoft.com/en-us/uwp/api/windows.data.json?view=winrt-26100

Clean full example is here: https://github.com/ioa747/NetWebView2Lib/pull/41

is there a way to use Windows.Data.Pdf in AutoIt ? https://learn.microsoft.com/en-us/uwp/api/windows.data.pdf?view=winrt-26100
