Okay, the problem seems to be the fact that you're calling shutdown.exe from a 32 bit process (I presume you're using the more popular 32 bit version of python, rather than the native 64 bit one).
Under 64bit windows, any call to a system32/* executable from a 32-bit process is silently redirected to syswow64\*, which contains 32 bit versions of (almost) all the executables. So when you call system32\shutdown.exe from your python process, Windows tries to call syswow64\shutdown.exe. Problem is, there is *no* 32bit version of shutdown available (syswow64\shutdown.exe doesn't exist), so your call ends up failing. tl;dr version - You can't call shutdown.exe on a 64 bit machine from 32 bit python Solutions: 1. Use the native 64 bit version of python 2. http://blogs.sepago.de/nicholas/2008/03/13/jailed-32-bit-processes-on-windows-x64/ On Tue, Dec 29, 2009 at 11:53 PM, ™aßlเίlαslเ ► <abhilash.p...@gmail.com>wrote: > Ya...
