Closed avnet78 closed 1 year ago

avnet78 commented 2 years ago

I am following the code provided in the opcsample/Program.cs and I am getting the below exception. Should I register any of the com dll's using regsvr? Please advise.

System.Runtime.InteropServices.COMException: 'Retrieving the COM class factory for component with CLSID {28E68F9A-8D75-11D1-8DC3-3C302A000000} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).'

These are the dll's inside the bin folder:

@aevi1103 @avnet78 If you want to use OpcAutomation or Graybox, you should register dll, and this is only support x86. If you want to support x64, you should use OpcNetApi and install OPC Core Components. Opc Da Introduction
