Simple Software Update: Creating a Setup Script

When you have a new update for your application, you may build it as a setup file in the form of an executable (.EXE) or a compressed cabinet (.CAB). By default, after downloading the update, the Updater automatically executes the downloaded file to install the update to the application. Besides, you may also configure the Updater to run a setup script instead to perform tasks needed to install the update. The script file can be VBScript (.VBS), batch (.BAT), or any executable file.

The following is a sample batch file that uninstalls the previous version, and then runs the downloaded setup file (Setup.exe) to install the new version.

@ECHO OFF

IF NOT EXIST Setup.exe GOTO END

ECHO Uninstalling the previous version ...

Msiexec.exe /x {01234567-89AB-CDEF-0123-456789ABCDEF} /quiet /passive

IF ERRORLEVEL 0 GOTO INSTALL

ECHO Uninstallation Error!

PAUSE

GOTO END

:INSTALL

ECHO Installing the update ...

Setup.exe

:END
