I have an application that loads itself into the tray.  How do I close it manuallly from an MSI file upgrade installation.  I would like to send the WM_CLOSE message to it.  Is there an easy way to do this.

I don't think the installer can do this for you itself. You will need to write a small standalone program that does what you want then include it as a custom action in the installer project.

A simple custom action along these lines is all you need.

UINT _stdcall StopTheWindow(MSIHANDLE hInstaller)
{
 HWND hWindow;

 hWindow = FindWindow(WC_DIALOG, "The Window Name");
 if (hWindow)
 {
   PostMessage(hWindow, WM_CLOSE, 0, 0);
 }
 return ERROR_SUCCESS;
}
