Question about unattended or silent uninstallation

[MauricioDeAbreu]

Buenas días amigos.

Tengo una duda con respecto a la desinstalación de un programa desde un archivo Batch

La única forma en que puedo ejecutar la desinstalación del programa es mediante esta linea que extraje del UninstallString del editor de registro.

rundll32.exe dfshim.dll,ShArpMaintain ComponentesHarware.application, Culture=neutral, PublicKeyToken=b3fd472d4be1fc0f, processorArchitecture=msil

Pero no encuentro una manera de hacer que la desinstalación sea sin intervención del usuario, ya que al ejecutar la linea muestra la ventana de desinstalación pero pide la confirmación (aceptar).

Use el parámetro /S pero me da error, diciendo que el programa no se ha podido desinstalar.

Hay alguna forma de lograr que se realice la desinstalación sin que pida darle a aceptar ?

De antemano muchísimas gracias por el apoyo.

Good morning friends

I have a question regarding the uninstallation of a program from a Batch file

The only way I can execute the uninstallation of the program is through this line that extrajects from the uninstallstring of the registration editor.

rundll32.exe dfshim.dll,ShArpMaintain ComponentesHarware.application, Culture=neutral, PublicKeyToken=b3fd472d4be1fc0f, processorArchitecture=msil

But I can not find a way to make the uninstallation it is without user intervention, since when executing the line it shows the uninstall window but asks for confirmation.

Use the / s parameter but it gives me error, saying that the program has not been uninstalled.

Is there any way to get the uninstallation without asking to accept?

Thank you very much for the support.

You have not indicated the way to provide the confirmation... If it is just the Enter key, try:

Code: Select all

echo/| rundll32.exe dfshim.dll,ShArpMaintain ComponentesHarware.application, Culture=neutral, PublicKeyToken=b3fd472d4be1fc0f, processorArchitecture=msil

If it is a "S" key, try:

Code: Select all

echo S| rundll32.exe dfshim.dll,ShArpMaintain ComponentesHarware.application, Culture=neutral, PublicKeyToken=b3fd472d4be1fc0f, processorArchitecture=msil

If this don't works there are still other options...

Try this:

Code: Select all

@if (@CodeSection == @Batch) @then


@echo off

rem Use %SendKeys% to send keys to the keyboard buffer
set SendKeys=CScript //nologo //E:JScript "%~F0"

rem Start the other program in the same Window
start "" /B rundll32.exe dfshim.dll,ShArpMaintain ComponentesHarware.application, Culture=neutral, PublicKeyToken=b3fd472d4be1fc0f, processorArchitecture=msil

rem Enable next line if there are synchro problems
REM ping -n 4 localhost > NUL

rem Send the ENTER key
%SendKeys% "{ENTER}"

goto :EOF


@end


// JScript section

var WshShell = WScript.CreateObject("WScript.Shell");
WshShell.SendKeys(WScript.Arguments(0));
