That's strange. It says it can't import a module named meraki, however if you ask it to list the modules it does have, it shows the module. Does not compute.
What does your windows PATH environment variable look like?
If you want to use the "old code" (0.34 I believe), you can replace "from meraki import meraki" with "from meraki import legacy". I ran into this issue before because I had a file name meraki.py I was trying to use. Since you are using it straight from Python itself, that's an odd error.
