SAP.Connector.RfcCommunicationException

Hi,

I tried deploying a windows application that connects to an RFC-enabled function module (using SAP .NET Connector). I already installed the .NET framework and librfc32.dll as indicated in the help topic.

Unfortunately, i still get the ff. error when i tried using the program: SAP.Connector.RfcCommunicationException: Connect to SAP gateway failed....

What did i miss? Does the client machine need a SAP GUI installed for it to run an application that uses the SAP.NET connector? Do i need to put the SAP.Connector.dll and the SAP.Connector.RFC.dll in system32 as well?

Any insights is greatly appreciated. Thanks!
