I have 64 bit Windows 7 machine and just downloaded the latest standard distribution release (7.1) from the Neuron website.NEURON: When you press the Download button you will be asked to save the file in a directory. At this point if you want you can change the name of the file. First you expand the file with the unzip program supplied with NEURON or any other zip program. If you do not already have NEURON click here to go to the download and install NEURON page.
Then cd to the directory that contains the mosinit.hoc file and if under unix type nrnivmodl and press enter to compile the mechanism (.mod) files. If under windows run mknrndll to compile the mod files. On the mac drag the model folder to the mknrndll application. Then the model is ready to be run. A default way to run the model is given by the mosinit.hoc file (which is executed on startup during Auto-Launch) and is executed by either double clicking on the file (PC or MAC) or by typing nrngui mosinit.hoc on the command line (PC or unix). Check the readme file for more information on running the model.
I downloaded the zip file of the model I would like to use and have all relevant .hoc, .mod, etc files in a directory C:\Neuron\model_name. When I open mknrndll, I am prompted to choose a directory. I select this directory and click "Make nrnmech.dll." I immediately get an error message on the black window (with mknrndll in the title bar):
