I'm trying to install SAP .NET Connector (version 2.0). When I try to install this, I get a prompt that I need to install .NET Framework 1.1.4322. In my machine I already have .NET Framework 3.5 installed. Do I need to install .NET Framework 1.1.4322 to install SAP .NET Connector? Will .NET Framework 3.5 not be sufficient?
