Links to older versions are not public but I will send you an email (to the address you used to register with these forums) with the link. It is version 5.34.

Unfortunately, I cannot provide such an image available straight away. It may take a bit of effort, but this problem seems to be wide spread and we could reproduce it on everyone's laptop with the configuration I provided before.

Would you be able to provide an older version which does not rely on the 3rd party library causing this problem? and I will install the prerequisites myself.

Thank you.

The problem seems to be related to loading the mixed-mode assembly (written in C++/CLI) that does the actual OPC communication. There are two of them - one for x86, one for x86. And, they require a corresponding set of Microsoft Visual C++ runtime libraries be present on the system. In order to save our users from having to install these redistributables, we use a special approach that involves "virtualizing" the necessary files in memory. We use a 3rd party library for that, and it looks like that there is a native code exception, possibly in that library, that takes the whole process down immediately. What precisely happens, and why only on your systems, I do not know at the moment.

The library is not under our control, and we cannot even reproduce the problem here. We can try to contact the authors of the library for help.

I assume you don't happen to have a virtual machine image with this problem present?

Thanks for your response.

1. I am using Windows 8.1 Pro with 64-bit OS.

2. Yes. I have tried try/catch but it didn't catch any exception. Instead, it simply exits on this line "var client = new EasyDAClient();"

3. I compared the debugger outputs. There seems to be a problem with loading App_Web_OpcLabs.EasyOpcClassicRaw.x86.dll. Please see the debugger outputs below.

4. C# in VS2013.

The same problem occurs on my colleague's laptop too with the same development environment.

Yes, it should be possible. We have customers that do just that. I have now made a test on two systems, and it also worked. Of course I trust you that you do have this problem - but at the moment I cannot reproduce it or give an advice.

Some questions:
1. Which Windows version are you using? (and, I assume it is a 64-bit system, right?)
2. Have you tried to put try/catch around the problematic statement and see if there is an exception?
3. Have you tried to look at/capture the contents of the debugger Output window to see whether there aren't any interesting messages?
4. Which version of Visual Studio are you using? Are you developing in C#?

Thank you

Can't run when target platform is x86 or Any CPU with Perfer 32-bit checked was created by Chen
I have version 5.35 installed on my pc. Reading your documentation, I think I should be able to build my application with target platform set to x86. But running your QuickOpcCSharpExmaples solution straight out of the box, I can't get any project to run when I set the configuration to x86 or Any CPU with Prefer 32-bit checked. It builds successfully, but when I try to debug it, it just exits when initialising EasyDAClient.
