I have an error 340 allready when i made this order in my visual basic program (in my customer).

    Set PDFCreator1 = New clsPDFCreator

I haved install the last version of PDFCreation and the server is à Windows 2003 server for small business server.

I have also installed the MDAC 2.8 version. All of my special visual basic DLL are updated correctly.

I do not know what to do.
