Summary

Synopsis

This article is for Basic MSI and InstallScript MSI project types.

This article discusses a way to detect if a setup is being run from the Add/Remove programs.

Discussion

This can be done by following these steps:

1. Add a property to the CmdLine entry of setup.ini, such as:

   CmdLine=NOTADDREMOVE=1

2. In the script, use the MsiGetProperty function to get the value of NOTADDREMOVE.

3. If the value is 1 (as specified in the INI entry), it can be determined that the user is running the uninstallation from the media. Otherwise, setup.exe was not used to launch the uninstallation, in which case the user is uninstalling from the Add/Remove Programs applet in Windows.
