Python Error "WindowsError: [Error 127] The specified procedure could not be found"

I'm running a python script importing dataextract (from tableau api) csv,os, and datetime when I run it I'm getting this error and I don't know where to start looking.The only line of code I am running is

import dataextract as tde

And I installed this library following tableau's tutorial http://www.tableausoftware.com/learn/tutorials/on-demand/extract-api-introduction?signin=f850b055b106d24b93b365faad64838f

I have faced the same problem while working with Python 2.7 and this is what I found:

-- Problem was coming because I have installed multiple versions of python (Python3.2, Python3.5 etc).

-- Because of multiple versions, at runtime there was multiple DLLs with same name (in all python versions library). So it was unable to figure out which one to load.

Solution: I have uninstalled all python versions except one I needed (Python2.7) at time. Then run the program and now everything was working fine for me.

After trying everything I found that the Tableau Extract Library only works on computers were Tableau is installed
