Hello,

When I am trying to build a simple Web Automation flow to complete a Web form filing task, I get an error message.

This error message occurs when I work with the "Focus Text Field on Web Page" and try to add a UI Element. The browser I am using (Edge) does have the Windows Power Automate extension installed on it.

The error message is shown below:

Message = The hook procedure is not installed
Error = System.ComponentModel.Win32Exception
