Hello.

Can you please ask the customer to install/reinstall OPC Core Components, making sure they use the 64-bit package?

The file is here:  opcfoundation.org/developer-tools/samples-and-tools-classic/core-components/   , name is "OPC Core Components Redistributables (ZIP/MSI/MSM)".

After unpacking, double-click on "OPC Core Components Redistributable (x64) 3.00.108.msi" and let it install for all users.

Best regards
 

Hi,

Our client is using the DeltaV OPC DA server. When he tries to browse for OPC items, he is getting the following error. Browsing with Matrikon OPC Explorer works fine.
