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

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

Unhandled crash in C# Application was created by andrew_k
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.
