Unable to load driver DLL 'C:\Program Files\National Instruments\Shared\NI OPC Servers\drivers\dataforth_isolynx_u.dll'

[Lily1979]

Bonjour,

Quand j'ouvre NI OPC server, il y a un message qui dit "Unable to load driver DLL 'C:\Program Files\National Instruments\Shared\NI OPC Servers\drivers\dataforth_isolynx_u.dll'".

J'essaie de comprendre le fonctionnemnt de OPC server en utilisant le simdemo.opf, mais apparemment ça ne marche pas.

Aussi au cours de l'installation des modules DSC, j'ai eu un message d'erreur, voir la photo.

Quelqu'un a une idée?

Merci.

Lily

Hi Lily

 The error during the installation of DSC is caused by a bug in the installation of microsoft's SQL server. It is caused by the fact that you are running a non-english windows version. During the setup, it tries to overwrite a localized file with an English version of the file, which is not allowed. It can be safely ignored however by just clicking OKand continuing the setup (see http://support.microsoft.com/kb/958897 for more details).

Regarding the OPC server:

What version of our OPC server are you using? In previous versions, there was a known issue where certain drivers (like the dataforth isolynx) were not included. So could you first check the folder if the dll file is there or not? If it is there I suggest you to check the following forum post as it might also be a solution in your case:
