Hello
I stumbled on this bug by having to delete multiple rows in an .xls file using modern Excel activities.
Under normal conditions, removing multiple rows by inputting “1, 3” for row1 and row3 worked fine, but when I unchecked the “Use system separator” checkbox in Excel Settings (I need to set specific separators for this process) I kept getting an error causing an “Exception from HRESULT: 0x800A03EC”.
I solved this issue by separating the “delete row” activity to two different activities, one for each row:
Hope this can help.
