Util:CloseApplication not working

[Steve0212a]

I am using the newly release v4 WIX - Congrats on getting that released!

I am trying to close two applications before upgrade or uninstall.

Inside my Package node, I added this:

    <util:CloseApplication Id="CloseUI" Target="prog1.exe" CloseMessage="no" RebootPrompt="no" />
    <util:CloseApplication Id="CloseUtility" Target="prog2.exe" CloseMessage="no" RebootPrompt="no" />

However, when I do an upgrade, nothing is closed. I do see this in my log file:

MSI (s) (48:C0) [13:05:33:950]: Doing action: Wix4CloseApplications_X64
Action ended 13:05:33: CreateFolders. Return value 0.
MSI (s) (48:50) [13:05:33:952]: Invoking remote custom action. DLL: C:\Windows\Installer\MSI92DC.tmp, Entrypoint: WixCloseApplications
Action start 13:05:33: Wix4CloseApplications_X64.
MSI (s) (48:C0) [13:05:33:959]: Doing action: InstallFiles
Action ended 13:05:33: Wix4CloseApplications_X64. Return value 1.

Am I missing something? I confirmed that my exe names are correct by running taskkill.exe with the exe names to verify they are killed.

thx

You turned off the default behavior, so there's nothing for it to do.
