Question

Is there any python script to install a msi? I need to install msi and run it without showing any dialogue modal. I have msi on my folder c:\\user\\documents and i have a wxpython GUI developed using python script.I need to silent install msi and run the exe from the GUI.

Answer 1

simple use. No transforms provided, and code is non-blocking:

import os
os.system('msiexec /i %s /qn' % msi_location)

With transforms, and code is non-blocking:

import os
os.system('msiexec /i %s TRANSFORMS=%s /qn' % (msi_location, transforms_location)

With transforms, and code is blocking - so you know when it has completed:

import subprocess
subprocess.call('msiexec /i %s TRANSFORMS=%s /qn' % (msi_location, transforms_location), shell=True)

Answer 2

This is not really a python question, and it depends if your specific MSI package allow unattended installation. See this SO article

detect msi parameters for unattended install

how to find out about the parameters of an MSI package. Then, try the unattended installation manually using the windows command shell, calling msiexec . See here

for more information.

Finally, all you need to do in python is to use os.system to call msiexec with the name of the package and the correct parameters.
