I'm having an unusual problem lately that when I open some excel/word document and try to connect to it's process using -
app = pywinauto.Application(backend="uia").connect(process=19812)
It seems not to work, meaning that app.is_process_running() returns False and the top_window() method raises the RuntimeError(No windows for that process could be found) exception.
But if I run the actual executable program (Winword.exe or Excel.exe and not some *.xls file), it seems to work properly and everything seems to work fine.
I checked the UIA compatibility with inspect.exe on the documents and everything seems to be fine.
What can be the problem here?
