I am getting this popup when trying to automate from a desktop app:  
“We detected that you are trying to capture in a Java window that uses a custom JRE, Would you like to install the Java Support Files?”

I close the Java app & install the support files. It states installation complete, but then i get another error:  
“Invalid UI Node”

When I open the app & try to use a dropdown, I get the same request to install Java support files.

I am using Enterprise Licensed 2019.10.4.

Any help would be greatly appreciated.

Thanks  
Bill

All, Posting my own solution here. At ;east it worked for me. By simply checking the SendWindowMessages box on the selector it worked fine without the Java support files.

Thanks
