Hello.

In such case you install the redistributable, and it works then. That's what the documentation is trying to tell you.

Regards

Hi,
it seems that I can't get work my app OPC UA without the Visual C++ Redistribuable Package in the production environment.
QuickOPC version 2016.2

In the development environment I don't have any problem.
The documentation doesn't ask for this package, but without it doesn't work.

What's the right way to accomplish the deployment?
