using LabVIEW 5.0.1f1 to control Excel 97 under WinNT, but when I build up my application in a executable, it doesen't work. I've also tried with a library (llb) and LabVIEW Runtime Engine, but it seems not to work but in development mode. Any suggestions?I'm just opening Excel, creating a new excel workbook, writing this workbooks worksheet, save it, and exiting Excel. When I build the executable, workbook creation seems not to work, returning error code 1. The new workbook name is inputed using a a file dialog(if empty, but allways empty). All of this is done via activeX. An example is attached, works fine in development mode.
