Hi there, this is a rookie speaking.
I encountered this error code even after generating the repair plan.
Any thoughts on the reasons for the failure?

Full Error Code:


Source: Use Excel File

Message: Error opening workbook. If Excel is installed, run the ‘Repair Tool for Microsoft Office Interop’ from the Tools tab on the Home screen.

Exception Type: UiPath.Excel.ExcelException

UiPath.Excel.ExcelException: Error opening workbook.

Thanks in advance!
