Simulating input on Remote Desktop does not work

[YangMin]

I tried to simulate key press on Remote Desktop. It does not work.
Error：
Some simulated input commands were not sent successfully. The most common reason for this happening are the security features of Windows including User Interface Privacy Isolation (UIPI). Your application can only send commands to applications of the same or lower elevation. Similarly certain commands are restricted to Accessibility/UIAutomation applications. Refer to the project home page and the code samples for more information.

How can I do?
Thanks!

Hi @YangMin
I did not try it out with Remote Desktop, but I will have a look.
In the mean time I did a quick research and came across https://docs.microsoft.com/en-us/previous-versions/dotnet/articles/bb625963(v=msdn.10)#uiaccess-for-ui-automation-applications , so maybe this might the issue.
Can you upload a small test-sample so that it easier for me to verify?
