Is the version in GAC also 5.23.1225.1 ?
Note: the very recent build (the one on the Web) of version 5.23 is 5.23.1371.1. However it is fine to work with an older one - as long it is the same both on the development computer and on the target computer.
Also, look at the "Precise Version" attribute on the references in your Visual Studio project. If it is "true", which I think will come as default, then the app must find the assemblies of the precise version as used during the build. You can set it to "false" to allow for loose version number checking.

But, I do not fully understand the description - can you please provide details? Specifically, is there anything on our side that we either did wrong, or at least could have done better (to prevent such errors)?
Thank you

Note that version 5.23 also needs Microsoft.Contracts.dll, i.e. not just everything that starts with "OPCLabs". I had a long exchange with a customer who insisted that all assemblies are installed, whereas in the end this particular one was missing.
Are there any details to the exception? No precise file indicated? Does it have InnerException?
Does the server have .NET Framework 3.5 installed? (if it has SP1 for the operating system, it will have it automatically, otherwise it's not guaranteed).

No good Result !!
I have copied all dll from OPCLabs\QuickOPC 5.2\Assemblies directly in the executable path c:\Programm Files(32)\TestOPC\
where I have 2 applications , EasyOPCNETDemo32.exe (32 bits ) and EasyOPCNETDemo64.exe (64bits)
The two app run on Seven 64 bits.
No good result on Server !!
Have you another Idea ?
Best regards

On the target computer, the QuickOPC assemblies need to be either in the GAC again, or in one of the codebase directories - usually, in the same directory as the .EXE of the app.
