Invalid product key-code
 

Good morning,
Starting from an application €œVB6€� our software has generated an excel file
through the creation of the object €œExcel Application€�(Code: CreateObject
€œExcel.Application€�).
Since today we never had any kind of problem about that, but some days ago
the software has begun to give a message error €œGood morning,
Starting from an application €œVB6€� our software has generated an excel file
through the creation of the object €œExcel Application€�(Code: CreateObject
€œExcel.Application€�).
Since today we never had any kind of problem about that, but some days ago
the software has begun to give a message error €œinvalid product key-code€�.
Please control the code written on the label.
The error appears only when the exportation is done from a remote session on
Windows Server 2003, where our Software is installed.
If the same kind of operation is done from the server there is any kind of
problem.
I have already tried to re-install Office 2003 but the problem still exists.

Can you explain me the origin of this kind of problem?
In the meanwhile thanks a lot.

Our Best Regards
