Hi Jim,
Thank you for reply.
I already use passing the path to the DLL call node before writing this post.
One strange thing is When i call the DLL directly from the node and don't add it in the project. There is no problem but i can't use this method because the dll need dependancies and they are not always installed on the customer computer. If i add the dll in the project, it's path is modified.
For the moment, i decide to have to edit the lvlib manually after installing the package. Maybe i can build a VI to do it with LabVIEW scripting.
Regards
