Hello.

In order to make the license purchase, visit www.opclabs.com/purchase/full-price-list . The easiest way is the choice (Web shop, credit card; license key generation is automated and usually happens within minutes).

Dear Team,

You are right.

the issue is resolved.

As you shared, after moving the certificate from Rejected folder to the UA Application folder in the same executable location, the issue was resolved.

Thanks for your support.

please share the procedure to purchase the license.

If you are targeting .NET Core, the certificate store directories are not the ones you have played with.
It is clearly documented in all the links I have provided. Please read it again.

The proper certificate store directories are "local", under the directory where your application executable is located.

Hello.

Does your application target .NET Framework or .NET Core? (please send a screenshot of the corresponding Project properties page - assuming that you are using Visual Studio - or a corresponding setting elsewhere).

Thank you

Hello.

If you trust that certificate, you should find it in the "Rejected certificate store" and move it into "trusted peers certificate store".

Dear Team,

Thanks for Quick OPC UA Support. I can execute the OPC UA Client application.

But, while starting the application, I am getting the user confirmation request. Please find the below image.



How can I respond to this request?

Should I load the server certificate in the application path?

How can I feed the OPC server certificate to the quick OPC application?

Would you please help me to overcome this issue?

with regards,
senthil?
