{
   BeforeUninstall += new InstallEventHandler(BeforeUninstallEventHandler);
}
private void BeforeUninstallEventHandler(object sender, InstallEventArgs e)
{
   // Add steps to perform any actions before the Uninstall process.

Well that is just a repeat of what you have already written above. You show some code but have not given us any idea of what your problem is.

Ok, however it is depends on the context. Do you want to simply do some logging? Or want to prevent to start your uninstaller twice? Are you interested in a specific application uninstaller running state? Or you like to know if ANY uninstaller started by something/someone?
More important, you like to modify your own code, or like to hook up on installer process belongs to someone.
I have a few idea, althought you should fill in more details if I may ask :)

You can override the Uninstall method: Installer.Uninstall(IDictionary) Method (System.Configuration.Install) | Microsoft Docs[^]

Overriding the Uninstall method simply enable your code to run instead of the original Uninstall method. I think the original question is about detect starting of any OTHER uninstalling process (not your program, but any other that is not based on your code and executable) and do some operation. Of course it would be helpful to know what was the true intention of Member 14369462
