Exception: CoCreateInstanceEx: Class not registered

[avnet78]

I am getting CoCreateInstanceEx: Class not registered Exception. Here's how I am trying to initialize the opc server:

Please advise.

var opcServerName = "FactoryTalk Gateway";
var opcServerIP = "192.168.200.7";

Uri url = UrlBuilder.Build(opcServerName, opcServerIP);

using (var server = new OpcDaServer(url))
{
  // read opc tags
}

Why bother with COM exception if there exists a simple and straightforward solution? That will make your life easier, I believe.

@avnet78 Did you ever get past this? I was able to by using the ClsId of the server, but the "name" property wouldn't work for me.
