Hello wapters,

I wonder if with wapt I can uninstall a software that was already on the computer before installing the client?

Yes, here is a sample code:

https://www.wapt.fr/en/doc/CreationPaqu ... -logiciels

Code: Select all

for soft in installed_softwares('winscp3'):
                run(WAPT.uninstall_cmd(soft['key']))

Sorry for the question, but I run this code in some place or save this as a wapt package and link to the computer or none of this?

As you said, you need to create a wapt package that will uninstall the software.

Okay. Like this?

setup.py

Code: Select all

# -*- coding: utf-8 -*-
from setuphelpers import *

uninstallkey=[]

def install():

    softname = 'firefox'
    check_installed_soft = installed_softwares(softname)
    if check_installed_soft:
             for uninstall in check_installed_soft:
                key=uninstall['1233A4A7-BA0B-4067-BE21-FB97AFABC0CF']
                if installed_softwares(uninstallkey=key):
                         run(WAPT.uninstall_cmd(uninstall['key']))

Your code works. I propose to simplify it:

Code: Select all

def install():
    if uninstall_key_exists('1233A4A7-BA0B-4067-BE21-FB97AFABC0CF'):
        run(WAPT.uninstall_cmd('1233A4A7-BA0B-4067-BE21-FB97AFABC0CF'))

sfonteneau,

This "key" is the value found in the column "Uninstall key" from Software Inventory in wapt console, right?

Yes!
you can also find the uninstallkey with this command: https://www.wapt.fr/en/doc/Utilisation/ ... t-registry

The second code I provided you can uninstall software that has the uninstall key "'1233A4A7-BA0B-4067-BE21-FB97AFABC0CF'"

This code bellow allows you to uninstall all the software that uses the word "winscp" in the information of their uninstall key.

Code: Select all

for soft in installed_softwares('winscp3'):
                run(WAPT.uninstall_cmd(soft['key']))

Now works!!! Thanks for the help sfonteneau!!!

The code for uninstalling only with the key, not worked, but with the code above, works like a charm!

In the end, the code is like:

Code: Select all

# -*- coding: utf-8 -*-
from setuphelpers import *

uninstallkey=[]

def install():
	for soft in installed_softwares('old_version_of_firefox'):
                run(WAPT.uninstall_cmd(soft['key']))

For new users, remember to create or copy the "control" and "wapt.psproj" files and place them inside the "WAPT" folder in the package root, ie along with the "setup.py" file.

After that, you need to build the package with the below command:

Code: Select all

wapt-get build-package <path of the files>

i.e.:

Code: Select all

wapt-get build-package c:\waptdev\test-remove-firefox
