Problem with Excel automation refnum

[chilly_charly]

While presenting ActiveX functions to students, I ran into an unexpected problem : only half of the PCs were able to work with Excel after the initial basic steps :

• place an automation refnum on the front panel
• right-click the automation refnum, then select ActiveX class, then select browse
• find Microsoft Excel objects library and select application
• connect an Automation open function
• etc...

What happened is that an error 3005 (Automation Open: Object specified is not creatable in ... ) was generated on half the machines, while everything was running smoothly on the others.
A workaround was to grab a working automation refnum control from the examples shipped with LabVIEW. The icon appears different and has a black arrow instead of the purple one got from the refnums palette. But even with this refnum, the problem could be reproduced when the activeX class was changed forth and back !

All the systems (Windows XP- LV 8.2) and machines were identical, configured initially from the same disk image.

Do you an idea of what's going on there ? Do you know where I  can get the black-arrowed automation refnum ?
