Presentationhost.exe

We are working with a .net solution that executes programs opening a window in Internet Explorer. The IE windows has embedded a Presentationhost.exe program that blocks any UI Element in the screen.
UIPath recognizes wnd elements within the Presentationhost.exe, but these cannot be validated by the IU Explorer. The only way it is working is via clipping region and tabs (inactive).

Is there a way to access to elements inside the presentationhost.exe?
