You only need to install the Navigraph data for the IXEG 737 correctly and it should work. There is nothing else to it.
Maybe try to run the installer that comes with Navigraph data again, paying close attention to the options? I think you need to pick the correct data format and also the correct installation path.
Which specific procedure is missing? You say a lot of them...that sounds like something went wrong with the installation, I think.
