Dear Hajo,
I had a issue when I tryed to save workbooks with a filename with extension .XLSX in stead of .xlsx. Close Workbook functione generates error 1430:
Possible reason(s):
LabVIEW: The path is empty or relative. You must use an absolute path.
<Not A Path>
Could you solve that, or add it in the white paper ?
Best regards,
Daniel
