OMNeT++ Simulating a project that references INET: 'cannot load library libINET.dll'

Question

I am trying to build and simulate a project that references INET (the INETWirelessTutorial actually), however I get the error below that says " Error: Cannot load library '../inet/src//libINET.dll': A dynamic link library (DLL) initialization routine failed". My project WireTryLiveson references project INET. I wonder if I need to link path environment variables differently? I tried the following:

Open "RSVPPacket.msg", modify it then change it back, and save it (which was suggested by a google group when I searched "libinet.dll")
Build INET

Neither seemed to work. INET Example projects simulate just fine.

What should I change so I can load libINET.dll?

You can see the libINET.dll here on the Project Explorer on the left.

Here are my environment variables.

Here's what the OMNET++ Console displays with my error:

Here's my omnetpp.ini:

*.host*.**.bitrate = 1Mbps

Here's my file wirelessTry.ned:

    }
    hostB: <hostType> like INetworkNode {

    }

}

First of all go to INET properties | OMNeT++ | Makemake | select src | Options... | Compile tab | More >> and ensure that you have set "Export include path for other projects" and "Force compiling object files for use in DLLs". And in Target tab set "Export this shared/static library for other projects". Then rebuild INET.

If it doesn't help, then try the following workaround:

In properties of your project (e.g. WireTryLiveson):
- select inet in Project References
- go to OMNeT++ | Makemake | select src | Options... | Target and select "Shared library (.dll, .so or .dylib)"
- go to OMNeT++ | Makemake | select src | Options... | Compile and select "Add include paths exported from referenced projects"
In Run | Run Configurations... of your project select opp_run and ensure that Working dir actually indicates the directory which contains omnetpp.ini.
