Win10 + Delphi 10.4 Sydney + QuickOPC 2019.1
(C) Win10 + Delphi 10.4 Sydney + QuickOPC 2021.2
My app reads a random value generating tag in every second.
( Matrikon.OPC.Simulation.1 /// Random.UInt1 )
I tested the behaviour in a separate Win10 environment with Matrikon OPC Simulation Server.
When I install 2019.1 runtime only
(A) runs OK
( runs OK
(C) gives Access Violation error (this is behaviour is OK)
When I install 2019.1 and 2021.2 runtime
