Using WiX, my install will optionally launch one of my installed program files when it completes. However, when my application is launched by the installer, it is usually not displayed in the foreground of the user’s desktop. It’s buried under other windows, so it’s not immediately clear to the user that the program is running.

I’ve tried having my program forcibly bring itself to the top when it runs, but that hasn’t changed the way it runs when started by the installer.

    Found a solution for this. I changed my CustomAction definition to use ‘FileKey’ rather than ‘BinaryKey’. I’m not sure, but I’m guessing that launching the application through a shell exec command was responsible for my application not being displayed in the foreground.

    <!-- old code -->
<CustomAction Id="LaunchApp" BinaryKey="WixCA" DllEntry="WixShellExec" Impersonate="yes" />

<!-- new code -->
<CustomAction Id="LaunchApp" FileKey="FooBarEXE" ExeCommand="" Return="asyncNoWait" Impersonate="yes" />
