I used to work with the Windows Task Scheduler every day, a few years ago; haven’t touched it in a while. So, today, I entered the appropriate info for General, Triggers, Actions, Conditions, Settings, and History. I am trying to open an XLSB file, which contains workbook open code in ‘ThisWorkbook’; code here: Private Sub Workbook_Open() Call GetFiles End Sub So, when I double-click the WB it opens just fine, the event triggers the macro, and everything is lovely. I can’t seem to make this work from the Windows Task Scheduler though. Frustrating. I see Excel open in the Task Manager!! For some reason, unbeknownst to me, WTS is NOT controlling the open event of this XLSB WB. Any ideas? Everything seems correct. I don’t get any error message. It seems like it runs, but it actually doesn’t run. Thanks everyone!!
