Crash with "ntdll.dll" error - by: federica

Hi,

I'm using QuickOPC COM, developing in C++.

On a pc of a customer I have some problem using my OPC client.
The machine continue reports crash with problems with "ntdll.dll".

The Quick OPC (2018.1) library is correcty installed and licensed.
The machine is Windows 10.

Have you never faced a problem like this?
What can I check?

Thanks
Federica
