Not able to download the excel file in Windows popup using AutoIT . Iam not getting any error message. Please guide me what mistake iam doing. I have manage to open and reach upto that page where it gives the popup asking for options – “open” or “Save” and with “OK” button at the bottom. But, after this nothing is happening and iam stuck. I need to click on “OK” button(as it is by default “Save File” radio button is selected). Thanks
