I have used the following code to import psspy(my psse is PSSE 35), however I have got the following error:

import os, sys
sys_path_PSSE = r'C:\Program Files\PTI\PSSE35\35.2\PSSPY27'  # or where else you find the psspy.pyc
os_path_PSSE = r'C:\Program Files\PTI\PSSE35\35.2\PSSBIN'  # or where else you find the psse.exe
os.environ['PATH'] = ';' + os_path_PSSE

The error:

import psspy
File ".\", line 56, in <module>
ImportError: DLL load failed: %1 is not a valid Win32 application.

could you help me with that? Thanks

Having a (v.35.2.1) install on default folders, I can load psspy with the following:

import psse35
import psspy

The error "ImportError: DLL load failed:" suggest a re-install.

Thank you @jconto. That problem was solved, but now I have "python load failed with error code 126" error for running the psse from python.

I wanted to put the code here, but it seems that the length exceeds the maximum length.

Any 'python load failed' error messages is usually related to bad installation. I can review your code if sent to
