Are you able to launch from the neurondemo icon? If this loads a nrnmech.dll (distributed with the installer) then we know if the problem is
in creating it or loading it.
By the way, we are talking about the new standard distribution,right? and not PyNEURON anymore?

Also, a search for load library 193 error code seems to suggest a 32 vs 64 bit problem. ie. 64 bit neuron cannot load a 32bit dll.
We can take this to email (michael dot hines at yale dot edu). Please send me the output of mknrndll after removing all the .c,.o,.dll files.

Hi BSCoventry,

I am currently having exactly the same problem - I was wondering if you had managed to resolve this?

Thanks!

This thread is stale. There have been a lot of changes since 2013. So it is necessary to diagnose from the beginning.
What is the version you are using?
Does the neurondemo work in the sense that you are able to select the "Release" demo and "Init&Run" is successful?
If you remove all the *.c, *.o, *.dll in your folder and rerun mknrndll, does it successfully create nrnmech.dll?
How do you launch and what is printed to the terminal window?
