I am glad it is solved. We do not manipulate OPCEnum security settings ourselves. But the QuickOPC setup program calls an installation of OPC Core Components from OPC Foundation, therefore my guess is that something went wrong there - we cannot influence that, though.

Hello.

Most OPC clients discover the OPC servers by means of the OPCEnum service. QuickOPC uses it as well, but when it fails, it falls back to registry (or Remote Registry) browsing. The hypothesis is that the OPCEnum is not working.

1. Can you please restart the machine to see if it helps.

2. Do you see OPCEnum in the list of running processes in the Task Manager?

3. Do you see OPCEnum in the list of Services? If so, does it shows with status being Running?

4. Do you see "OPC Code Components Redistributable" in the list of programs in Control Panel? If so, which version does it indicate?

5. Have you been able to see the OPC servers on that computer through OPC Explorer before installing QuickOPC?

6. How have you installed QuickOPC? Using its installation program, or by deploying its parts manually?

7. Is it a 32-bit or 64-bit operating system?
Thank you

OPC Servers disappeared after installation of QuickOPC was created by MSiatrak

Hello,

I have a strange problem after installing OPC labs on a target machine.

With use of any OPC Explorer I am not able to see any OPC servers installed on my machine. There are already installed 5 OPC servers, but after installation of OPCLabs they are not visible for only opc explorer software.

Application written with the use of OPCLabs library is working properly, but I am not able to use any OPC Client other that OPCLabs apps client!

I've installed QuickOPC-5.33.

The fast response will be appreciated!
