Handle is created but while trying open workbook, excel file is not opened and does not throw any exception. When I check processes on task manager, EXCEL.exe seems working. By the way, I can open the file from desktop. Is there anyone who face this kind of problem?   Wed, 29 Aug 2018 16:13:00 GMT https://community.blueprism.com/t5/Product-Forum/Unable-to-Open-Excel-Workbook/m-p/63136#M16125 Utku_CanGulen1 2018-08-29T16:13:00Z https://community.blueprism.com/t5/Product-Forum/Unable-to-Open-Excel-Workbook/m-p/63137#M16126 See if you maybe get some popup from excel, preventing opening the file, waiting for user input...

It was about file management authorization. Thank you all.
