Unable to Open Excel Workbook

[Utku_CanGulen1]

Hi All, In Excel VBO, "Open Workbook" code stage suddenly stopped to work. 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?

See if you maybe get some popup from excel, preventing opening the file, waiting for user input...

First create the Instance before Open Workbook, Create instance will ready your excel file to use in the background post that use Open workbook.

I've already created an instance and taken a handle. It was about file management authorization. Thank you all.
