Based on the QuickOPC version table ( kb.opclabs.com/Versions ), your only option would be to use QuickOPC 5.23 (a fairly old version). We do not, however, support this version generally, it has less features than the current versions, and bug fixes made to later version will never be projected back.

Best regards

Unfortunately, I have to run my OPC client application, which is written in C#.NET and uses the QuickOpc toolkit on this ancient OS version. My research shows that the latest supported .NET framework supported on this OS is 4.0. I can't seem to build my application targeting this earlier framework version, partly because the QuickOpc component is built with a later .NET version:

Severity Code Description Project File Line Suppression State
Warning The primary reference "OpcLabs.EasyOpcClassic, Version=5.41.1186.1, Culture=neutral, PublicKeyToken=6faddca41dacb409, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the assembly "App_Web_OpcLabs.EasyOpcClassicRaw.x86, Version=5.41.1186.1, Culture=neutral, PublicKeyToken=6faddca41dacb409" which was built against the ".NETFramework,Version=v4.5.2" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.0". OpcSocketService

Does anybody have a suggestion?

Thanks,
Brendan
