Error with sapno_utils when using SAP .NET Conector 3.0 in PDK 2.5 Runtime



I'm developing a .NET Portal Component by using the Portal PDK 2.5 and SAP .NET Connector. When I deployed to the NW Portal running the SAP Portal Runtime 2.5 Hot Fix3 on WindowsServer 2003 x64 and try to execute the IView for the application, I get the following issue:

Could not load file or assembly 'sapnco_utils, Version=, Culture=neutral, PublicKeyToken=50436dca5c7f7d23' or one of its dependencies. This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1) at SAP.Middleware.Connector.RfcConfigParameters..ctor() at

I think the issue is related to the following:

1. The server is running .NET Framework 2.0 x64

2. The SAP Portal Runtime 2.5 is a 32 bits application using the HotFix 3 to run on OS x64

3. Since the SAP Portal Runtime 2.5 is 32 bits app, I need to use the SAP .Net Connector version for 32 bits

4. When the sapnco_utils is used in the application, it is running in 32 bits, but it dependencies (C++ Native DLLs) are 64 bits since the .NET Framework 2.0 is the 64 bits version

Any help on this is very appreciated!
