What I meant is that the operating system is 64 bits.
Our product which uses your browsing component is a 32 bit program.

We have tried with our 32 bit program and also with your 64 bit Easy OPC client.

In both cases, the result is the same - exception and not possible to browse items.

Thanks,

Michael

You have answered to: "4. Does your client run in 32-bit or 64-bit process?" by "64 bits".
Now you wrote "Our program that is using your component is a 32 bit application."

I think this is a contradiction. Can you please clarify that.

All .NET binaries that come with QuickOPC are compiled for "AnyCPU" target. That is, they run in 32-bit process on 32-bit systems, and in 64-bit process on 64-bit systems. Changing them to always run in 32-bit process is possible either by a) opening the corresponding example solution (because they come with source code), changing the target CPU in project properties, and rebuilding, or b) patching the existing binary using the CORFLAGS utility, docs.microsoft.com/en-us/dotnet/framework/tools/corflags-exe-corflags-conversion-tool .

Proper registration is a task for the server vendor. Windows normally "reflects" the corresponding parts of the registry between the 32- and 64-bit worlds, so the component vendors do not necessarily have to do anything special, but it does not always work. First we need to establish whether the following two facts are both true: 1) all 32-bit local clients work and 2) no 64-bit clients work.

Our program that is using your component is a 32 bit application.

Do you have a 32 bit version of the EasyOPCClient demo program?

Can you please tel me if it possible to register the OPC server in the 64-bit part of the registry?

Thanks

Can you please, for test, rebuild the client application to run under 32 bits (target CPU = x86)?
It is quite likely that the OPC server has not registered itself in 64-bit part of the registry.

(I assume all other OPC clients that you have tested actually run in 32-processes, right? Note: Task Manager can show this).

Browsing OPC servers works fine.
Browsing OPC items fails - exception - Class not registered.
Read/Write to OPC items fails - exception - Class not registered.
Matrikon OPC Clients and other OPC client can browse OPC items.
64 bits
Client and server on the same machine.

Thanks.

Browsing OPC server is working
Browsing OPC tags - doesn't work - Class no registered.
Reading OPC item value - Class no registered.

It always happens.

64 bits

Client and server on the same machine. Only happens with DeltaV OPC server.

Thanks.

Hello.

You wrote "still struggling" - have we communicated about this issue before? If so, can you please point to a topic on the forums, or email (date)? Thank you very much.

Some questions:
1. Does it happen only with browsing, or with other OPC operations too?
2. Does it happen always, often, sometimes, rarely?
3. What about other OPC clients - can they browse?
4. Does your client run in 32-bit or 64-bit process?
5. Is the client on the same machine as the server, or is it via DCOM - remotely?

Best regards
