[SOLVED] Handling return code for uninstall
Published: June 8, 2023 - 9:45 AM

Hello,
I have a piece of software that installs correctly and enters the silent uninstallation key, but the return code is not 0.
What are the best practices for this type of problem?
Thank you in advance,
Thierry Rapp

Good morning
In this case, I advise you to clear uninstallkey after the installation:
SO :
This way wapt will forget the key
then create an uninstall function:
Code: Select all
def uninstall():
run('uninstall.exe',accept_returncodes=2)

I tested it:
The Uninstall method executed directly works
The remove me method returns another error
Code: Select all
# -*- coding: utf-8 -*-
from setuphelpers import *
app_uninstall_key = '{7261A53C-9352-45D1-8DE0-B326E177CA84}'
def install():
# Declaring local variables
fichier_lic=makepath('c:','ProgramData','itech','CESAR-LCPC','6.3','CDs')
fichier_nethasp=makepath('c:','CESAR-LCPCv2022.0','bin')
rep_syswow=makepath('c:','Windows','SysWOW64')
# Installing the software
print("Installing: CESAR-LCPCv2022.0.2.exe")
install_exe_if_needed('CESAR-LCPCv2022.0.2.exe',
silentflags='/b0 /q2',
key=app_uninstall_key,
min_version='2022.0',
timeout=600,
accept_returncodes=[0,12]
)
if not isdir(fichier_lic):
mkdirs(fichier_lic)
filecopyto('CESAR-LCPC_V6.3.ilicx',fichier_lic)
filecopyto('nethasp.ini',fichier_nethasp)
filecopyto('nethasp.ini',rep_syswow)
uninstallkey =[]
def uninstall():
uninstCMD = uninstall_cmd(app_uninstall_key)
print(uninstCMD)
run(uninstCMD,accept_returncodes=[0,12])
wait_uninstallkey_present()

Can you provide the error message?
I have a doubt about something...
Can you declare uninstallkey right before setup.py?
Code: Select all
# -*- coding: utf-8 -*-
from setuphelpers import *
uninstallkey =[]
app_uninstall_key = '{7261A53C-9352-45D1-8DE0-B326E177CA84}'
def install():
# Declaring local variables
fichier_lic=makepath('c:','ProgramData','itech','CESAR-LCPC','6.3','CDs')
fichier_nethasp=makepath('c:','CESAR-LCPCv2022.0','bin')
rep_syswow=makepath('c:','Windows','SysWOW64')
# Installing the software
print("Installing: CESAR-LCPCv2022.0.2.exe")
install_exe_if_needed('CESAR-LCPCv2022.0.2.exe',
silentflags='/b0 /q2',
key=app_uninstall_key,
min_version='2022.0',
timeout=600,
accept_returncodes=[0,12]
)
if not isdir(fichier_lic):
mkdirs(fichier_lic)
filecopyto('CESAR-LCPC_V6.3.ilicx',fichier_lic)
filecopyto('nethasp.ini',fichier_nethasp)
filecopyto('nethasp.ini',rep_syswow)
uninstallkey =[]
def uninstall():
uninstCMD = uninstall_cmd(app_uninstall_key)
print(uninstCMD)
run(uninstCMD,accept_returncodes=[0,12])
wait_uninstallkey_present()
I don't think that's it, but... if uninstallkey is empty, then wapt no longer has a key to test. If it continues to give errors, it means the key is still there

Oh yes, be careful when you're doing your tests; you absolutely must reinstall the program before testing a remove command, otherwise it won't work because the code isn't in the database! That might be the simple reason

I'm restarting the installation.
The program is uninstalled correctly; it's just triggering an exception.

Thank you for your feedback Thierry, we have made a fix for the exception message, it will be included in the next release 2.4.
I'm marking the topic as [RESOLVED].
Sincerely,
