Run Uninstaller
This command will delete the previous version of application from user’s computer. If you already have an installed version, you should create uninstaller using CreateInstall – do not run this command for deleting applications which were installed by other installers. Unlike uninstall.exe which executes using the Run Application command, this command waits for full completion of the process of deleting the application.
Uninstaller Executable File
Uninstaller, defined on Project – Uninstall page, will be run by default. Usually it is a #setuppath#\uninstall.exe. That’s why it is better to execute this command after an installation path has been chosen by the user. If your installation path is saved in the registry, then you can take the value from the registry and insert this path here together with the uninstaller file name.
#currentpath#\uninstall.exe #setuppath#\myuninstall.exe
