Hi there @Mraole,
Regarding your initial point, it appears the selector you used to attach the windows (which appears to be null) was not able to be found at the time of execution.

Would you be able to paste the selector utilised within your attach?

Onto your second point, this message occurs when UiPath is unable to generate a reliable selector, as in, a selector that will be robust in and of itself.

As such, it prompts you to select an anchor, an element which has a reliable selector, so it can use that as a reference point.

Thanks in advance,
Josh
