Following documentation example in https://docs.microsoft.com/en-us/power-automate/desktop-flows/how-to/identify-window-handle fails with error:

"Can't retrieve main window handle for application 'C:\Program Files\Microsoft Office\root\Office16\EXCEL.EXE'."

Hello Robpt,

Could you share your PAD 'Run Application' action details to me for reference? There's one old doc which refers to the same exception. I reckon you could try with it.

For some reason (probably after a computer restart), it now works, i can get the handle when launching Excel.
