Hello wapters,

I am doing a custom setup.py for the installation of miktex software, but after installation I can't uninstall via wapt.

Does the code below need any extra configuration?

Code: Select all

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

uninstallkey = []

def install():
	print('installing miktex v.2.9')
	install_exe_if_needed("basic-miktex-2.9.6643-x64.exe",
							silentflags="--shared --unattended"
							key='MiKTeX 2.9')

After installing your package, what is the output of the cmd command:

Code: Select all

wapt-get list-registry miktex

Looking at https://tex.stackexchange.com/questions ... miktex-2-9, it looks like uninstall can be achieved with

Code: Select all

uninstall_admin.exe

command.

So you could use this command in an uninstall() function in your package.

Something like:

Code: Select all

def uninstall():
    run(makepath(programfilesx86,r'MiKTeX 2.9\miktex\bin\x64\internal\uninstall_admin.exe --unattended'))

After installing your package, what is the output of the cmd command:

Code: Select all

C:\Users\carinha>wapt-get list-registry miktex
UninstallKey                           Software
                             Version             Uninstallstring

ktex/bin/x64/internal\copystart_admin.exe" "C:\Program Files\MiKTeX 2.9\miktex/b
in/x64/internal\uninstall_admin.exe"

In the uninstallation of miktex informs that it is ok, but in the "summary" appears

Code: Select all

Removed: cti_srt-miktexErrors: cti_srt-miktex

and in the client machine miktex does not uninstall.

If I manually execute the command:

Code: Select all

C:\Program Files\MiKTeX 2.9\miktex\bin\x64\internal\uninstall_admin.exe --unattended

still the manual uninstallation window appears and does nothing automatic.

It might be like this

Code: Select all

def uninstall():
    run(makepath(programfilesx86,r'"MiKTeX 2.9\mi
ktex/bin/x64/internal\copystart_admin.exe" "C:\Program Files\MiKTeX 2.9\miktex/b
in/x64/internal\uninstall_admin.exe"'))

You have to find the proper unattended switch to append to

Code: Select all

C:\Program Files\MiKTeX 2.9\miktex\bin\x64\internal\uninstall_admin.exe

so that it runs silently. It may be /s /SILENT --quiet -q or perhaps it has not been planned to be ran silently at all ...
The command which is registered seems to be broken as there is mixup of backslashes and forward slashes...

According to the miktex developer, only have the uninstall option via commnad line with the installer itself.

Code: Select all

miktexsetup uninstall

Tomorrow I'll try to remove it by running wmic through cmd.exe or rmdir in "C:\Program Files\MiKTeX 2.9".

I tried with the code below, but I get the error:

Code: Select all

Coping miktexsetupx64.exe and miktexsetup.exe to MiKTeX 2.9 folder...
NameError: global name 'programfilesx86' is not defined

Code: Select all

# -*- coding: utf-8 -*-

	filecopyto('miktexsetupx64.exe',makepath(programfilesx86,'MiKTeX 2.9'))
	filecopyto('miktexsetup.exe',makepath(programfilesx86,'MiKTeX 2.9'))
	if isfile(makepath(programfilesx86,'MiKTeX 2.9','miktexsetupx64.exe')):
		print('Files copied successfully!')
	print('Installing MiKTeX 2.9')
	install_exe_if_needed("basic-miktex-2.9.6643-x64.exe", silentflags="--shared --unattended")
	
def uninstall():
	print(u'Starting miktex uninstall...')
	if iswin64():
		print('Uninstalling x64 version')
		run(makepath(programfilesx86,r'MiKTeX 2.9\miktexsetupx64.exe uninstall'))
	else:
		print('Uninstalling x86 version')
		run(makepath(programfilesx86,r'MiKTeX 2.9\miktexsetup.exe uninstall'))
	print(u'Uninstallation of MiKTeX 2.9 completed!')

I do not know if the "filetocopy" part works the way I think.

I copied the two files miktexsetupx64.exe and miktexsetup.exe into the package folder, as I show in the image below:

https://image.ibb.co/k22rU7/wapt_pkg.png (img tag not working?!)

Is that so?
How to fix this? If the code is bad, you can contribute!

This looks fine
just replace programfilesx86 in your code by programfiles32

Code: Select all

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

uninstallkey = []

def install():
	print('Coping miktexsetupx64.exe and miktexsetup.exe to MiKTeX 2.9 folder...')
	filecopyto('miktexsetupx64.exe',makepath(programfiles32,'MiKTeX 2.9'))
	filecopyto('miktexsetup.exe',makepath(programfiles32,'MiKTeX 2.9'))
	if isfile(makepath(programfiles32,'MiKTeX 2.9','miktexsetupx64.exe')):
		print('Files copied successfully!')
	print('Installing MiKTeX 2.9')
	install_exe_if_needed("basic-miktex-2.9.6643-x64.exe", silentflags="--shared --unattended")

def uninstall():
	print(u'Starting miktex uninstall...')
	if iswin64():
		print('Uninstalling x64 version')
		run(makepath(programfiles32,r'MiKTeX 2.9\miktexsetupx64.exe uninstall'))
	else:
		print('Uninstalling x86 version')
		run(makepath(programfiles32,r'MiKTeX 2.9\miktexsetup.exe uninstall'))
	print(u'Uninstallation of MiKTeX 2.9 completed!')

I change a litthe bit the script.

Code: Select all

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

uninstallkey = []
destdir = makepath(programfiles32,'miktex_setup')

def install():
	print('Coping miktexsetupx64.exe and miktexsetup.exe to MiKTeX 2.9 folder...')
	mkdirs(destdir)
	filecopyto('miktexsetupx64.exe',makepath(destdir,'miktexsetupx64.exe'))
	filecopyto('miktexsetup.exe',makepath(destdir,'miktexsetup.exe'))
	if isfile(makepath(programfiles32,'miktex_setup','miktexsetupx64.exe')):
		print('Files copied successfully!')
	print('Initializing installation of MiKTeX 2.9.')
	install_exe_if_needed("basic-miktex-2.9.6643-x64.exe", silentflags="--shared --unattended")
	
def uninstall():
	print(u'Starting miktex uninstall...')
	if iswin64():
		print('Uninstalling x64 version')
		run(makepath(programfiles32,r'miktex_setup\miktexsetupx64.exe uninstall'))
		remove_tree(destdir)
	else:
		print('Uninstalling x86 version')
		run(makepath(programfiles32,r'miktex_setup\miktexsetup.exe uninstall'))
		remove_tree(destdir)
	print(u'Uninstallation of MiKTeX 2.9 completed!')

When I try to uninstall the mkitex, the below errors occur:

Starting miktex uninstall...

Is the error on the part of miktex or wapt?

Any feedback about my last question?

Hi Empbilly,

There are 2 issues...
The first one is your code
The second one is my code...

As there are spaces in the program path you try to run, cmd expect that you place the path inside double quotes.
So there is a message telling that the program "c:\Program" does not exist.

Something like...

Code: Select all

def uninstall():
	print(u'Starting miktex uninstall...')
	if iswin64():
		print('Uninstalling x64 version')
		run(ur'"%s" uninstall' % makepath(programfiles32,'miktex_setup','miktexsetupx64.exe'))
		remove_tree(destdir)
	else:
		print('Uninstalling x86 version')
		run(ur'"%s" uninstall' % makepath(programfiles32,'miktex_setup','miktexsetup.exe'))
		remove_tree(destdir)
	print(u'Uninstallation of MiKTeX 2.9 completed!')

could work.

The second issue is that the error message is not plain ascii but encoded, and my code does not decode properly, thus the "'ascii' codec can't decode byte 0xc3 ..." second message
