Usually this error is caused by a missing library reference.

Here are suggested steps to solve this problem. They might not be exact as I don't have Excel 2007 where I am right now.

1. Open the Visual Basic editor (Alt + F11 ???)
2. Open Module1 in SaveDBFIV
3. In the Tools menu choose References.
4. If there are any items in the list that are marked as MISSING, deselect them. (Write them down for future use)
5. Save and try again
6. If that does not fix the problem, you might need to try and find a similar library to the missing one in the list and select it.

I'm not sure how Excel labels things in French, but hopefully it is similar.

If this doesn't work, please post which references were labeled MISSING. If there were no missing references, please post all of the references that are selected.

Bonne chance
