unable to call exe using python

Question

I am calling an exe (which is dependent on other batch files) , Python is giving error. I am able to call exe (which is independent)

what I am doing is..

import os
os.system("notepad.exe")    # is working

but

os.system("c:/ank.exe")     # this is giving error as ank.exe is dependent on other batch     files

What error? More details please.

you have to first change the current directory so that the executable you want to run can find its dependencies:

target = "c:/ank.exe"
os.chdir(os.path.dirname(target))
os.system(target)

otherwise, os.system() executes in the directory of the running script.

I did that still os.system is returning 1, and no output is getting displayed.. Actually I am calling OpenEv.exe(converted openEV batch file to exe) and the path for that is target = "C:/Program Files/FWTools2.4.7/openev.exe" and the rest of the steps as same as you have mentioned still i doesn't work
