zmq.connect() function failing for ipc transport on windows 7

I'm working through the examples in 'Node.js the Right Way' and when executing the Router-Dealer example in Chapter 4 on Windows 7 with node.js version v0.10.29 , I get this error Protocol not supported when executing

 let responder = zmq.socket('rep').connect('ipc://filer-dealer.ipc');

I have read many entries on the 0MQ site, and the only hint I have is that the ipc file filer-dealer.ipc is not being created since I can't find it. The description of IPC indicates if the directory does not exist, an error is thrown. In this case, the file should be created in the directory where the .js files are. There have been other examples in the book that require a file be read, and I rewrote an example to write new contents to a file so it doesn't appear to be read/write permissions. I've looked in the book errata, but no mention was made. Any idea where to look? Thanks
