2. "it seem that doesn t works " - what precisely have you done and what were the symptoms?
3. Which version of QuickOPC you were usiong in this test?

Officially, QuickOPC 2020.2 does not support Windows 7. We remove support for systems that are no longer supported (by Microsoft, in this case).
Technically, it should most likely work just fine. But if you are using the installer, you will need to bypass it or fool it into thinking it is on a newer system, because it tests for the OS version and will refuse to install on older systems.

Best regards

We have seen issues on Windows 10 version 2004, and they were usually caused by a 3rd party library (BoxedApp SDK) we are using. Newer QuickOPC versions are updated to newer library, so hopefully that should be resolved.

If you need to stay with QuickOPC 2019.2, try this: kb.opclabs.com/How_to_disable_prerequisites_boxing .

You need to place a file next to the application's EXE (in the output directory where Delphi runs it from), and name it same as your EXE but with extension .EXE.CONFIG. The file contents, for QuickOPC version 2019.2, should be:
Code:
<?xml version="1.0" encoding="utf-8"?> <configuration> <appSettings> <add key="OpcLabs.EasyOpc.Implementation.Native.Assemblies.EnableVC140RedistBoxer" value="false"/> <add key="OpcLabs.EasyOpc.Internal.OpcPSBoxing.EnableOpcCorePSBoxer" value="false"/> <add key="OpcLabs.EasyOpc.UA.Toolkit.ClientServer.UAClientEngineBase.EnableUACertificateGeneratorBoxer" value="false"/> </appSettings> </configuration>
