What is the behavior of other QuickOPC-based applications on the same computer please? For example, can you run the Demo application supplied with the product just well, or does it also crash?

Thank you

Thank you. Is Windows 8.1, 64-bit on any other computer that does work well?

Sorry I should have provided this information. We are using the version 5.35 of QuickOPC, installed using the .Net option in your installer. We are using C# 4.5.1 on Windows 8.1 64 bit. Running on a Core i7 7702HQ equipped laptop with 16gb RAM.

Hello, can you please provide some additional information?:

1. QuickOPC version and build.
2. Operating system used, and whether it is 32-bit or 64-bit. Is it the same system as used on other machines that do work, or a different one?
3. Are you installing with the help of the QuickOPC's Setup.exe, or using your own installer?

Thank you

We have a .Net service (C#) in which the process on one of our test systems disappears on the line:

EasyDAClient _Client = new EasyDAClient();

Wrapping this in a try/catch block (including an empty catch clause which should handle some Win32 exceptions) makes no difference. Stepping through with a debugger gives us the same result: the process disappears at that line.

The relevant content from the Visual Studio Output window is below:

The program '[10380] ServiceApp.Service.vshost.exe' has exited with code -1073741790 (0xc0000022).

The final error code means 'A process has requested access to an object but has not been granted those access rights.' We checked for possibilities using: neosmart.net/wiki/0xc0000022/ but to no avail. The permissions are set and the files exist. We have also tried completely uninstalling the OPC application and reinstalling. Again, this didn't fix the issue. This only happens on one machine. Any help appreciated.
