ImportError: DLL load failed: %1 is not a valid Win32 application

edit

I had installed PyCharm (an IDE) to work on python scripts. I set the project interpreter of PyCharm to Anaconda since it has a large number of available python libraries.

When I run PSSE from PyCharm the following error occured:

import psspy ImportError: DLL load failed: %1 is not a valid Win32 application

When I changed project interpreter of PyCharm to Python 27, it worked very well with no errors.

Question: Is there something I need to install in PyCharm or Anaconda to run my codes smoothly?
