You are welcome. It is recommended that you put a 'using' directive at the top of your code file, in order to make it easier to reference QuickOPC objects. There are multiple namespaces needed, but you can start with
using OpcLabs.EasyOpc;
using OpcLabs.EasyOpc.DataAccess;
You can then simply write
EasyDAClient.SharedParameters.ClientParameters.UseCustomSecurity = false;
and also many other statements will become shorter.

Best regards

Thank you for your fast response!
After tinkering around I finally found the right line of code I had to use in my MainForm_Load:
OpcLabs.EasyOpc.DataAccess.EasyDAClient.SharedParameters.ClientParameters.UseCustomSecurity = false;

is doing the trick. Now I can finally test and evaluate QuickOPC.

Again, thank you for you great support!

Yes indeed, EasyDAClient does not contain ClientParameters. If you look carefully at preceding posts, you will find that EasyDAClient contains SharedParameters which in turn contain ClientParameters.

In addition, be aware that SharedParameters is a *static* property on the EasyDAClient class itself. That it, you need to use the type name (easyDAClient) itself (EasyDAClient.SharedParameters.ClientParameters), and *not* the variable that holds your instance of the EasyDAClient type.

where exactly do you add these additional codelines?
I am having a hard time figuring that out...

I always get the error that EasyDAClient does not contain definitions of Clientparameters.

We started trying the combinatinations and the line
EasyDAClient.SharedParameters.Client.UseCustomSecurity = false;
Worked for us too.

Can you please try to assign different combinations to following static properties - in the code, before the very first OPC operation is attempted:
EasyDAClient.ClientParameters.UseCustomSecurity 
EasyDAClient.ClientParameters.TurnOffActivationSecurity 
EasyDAClient.ClientParameters.TurnOffCallSecurity

[ADDED LATER: TurnOffCallSecurity only has any influence when UseCustomSecurity == true.]

Another update I found Interop.OPCAutomation.dll out in the internet and just to check I tested an OPC client with this and it also works.
