Fix NSIS Error Launching Installer – Complete Guide

NSIS Error is a common problem that arises while installing software on Windows Operating System. In this article, we provide a complete guide on how to fix the NSIS Error Launching Installer issue.


import subprocess

def uninstall_program(program_name):
"""
This function uninstalls a program by name.
"""
try:
subprocess.call(['C:\Program Files\Common Files\InstallShield\Driver\8\Intel 32\IDriver.exe', '/M{PROGRAM-CODE}', '/uninstall'])
print(f"{program_name} has been uninstalled successfully.")
except Exception as e:
print(f"There was an error uninstalling {program_name}. Error: {e}")

In the above code, we're using the `subprocess` module to call the `IDriver.exe` program that's typically used to uninstall programs on Windows systems. We pass in the program code for the program we want to uninstall as a parameter. If there's an error, we catch it and print an error message. If the uninstallation is successful, we print a success message.

Note that the `PROGRAM-CODE` in the code above should be replaced with the actual code for the program you want to uninstall. You can find this code by running the following command in the Windows command prompt:

wmic product get name,identifyingnumber

This will list all the programs installed on your system along with their identifying numbers. You can use the identifying number for the program you want to uninstall as the `PROGRAM-CODE` parameter in the `subprocess.call()` function.
