Jenkins executing python script

Question

I am trying to call python script using Jenkins. I am able to execute the python script over command promt successfully. However when same script is called over Jenkins, I am facing problem of dll. My script is as follow

import isystem.connect as ic
import time
import os
print('isystem.connect version: ' + ic.getModuleVersion())
# 1. connect to winIDEA Application
pathTowinIDEA = 'C:/winIDEA/iConnect.dll'
cmgr_APPL = ic.ConnectionMgr(pathTowinIDEA)
cmgr_APPL.connectMRU('U:/winIDEA/Winidea_cust_config.xjrf.xjrf')
debug_APPL = ic.CDebugFacade(cmgr_APPL)
ec = ic.CExecutionController(cmgr_APPL)
print('APPL Configuration launched')

Error is appearing at line 9: cmgr_APPL.connectMRU('U:/winIDEA/Winidea_cust_config.xjrf.xjrf')

Error message in Jenkins: E:6 Can not load iConnect.dll: 'C:/winIDEA/iConnect64.dll' SystemError: 'The specified module could not be found.

I have verified that iConnect64.dll is present at this path. How to resolve it ?
