You need to add shell=True to execute anything which isn't a binary
executable (EXE).

subprocess.Popen() and a .msi installer

2010-12-17 Thread Sebastian Alonso 
Hey everyone, I'm working on a script which uses subprocess to launch a
bunch of installers, but I'm getting problems with .msi installers although
.exe ones work fine. The output I get is this:

 import subprocess
 p = subprocess.Popen('python.msi')
Traceback (most recent call last):
File pyshell#1, line 1, in module
p = subprocess.Popen('python.msi')
File C:\Python25\lib\subprocess.py, line 593, in __init__
errread, errwrite)
File C:\Python25\lib\subprocess.py, line 793, in _execute_child
startupinfo)
WindowsError: [Error 8] %1 no es una aplicación Win32 válida


Has this ever happen to any of you? The idea is to get this running, make it
an exe (with py2exe) and use it whenever I need to install my whole
development environment in the right order.

Thanks in advance to all of you.

msi files are not executables. You need to use msiexec to run them.
