[wix-users] Stopping an application during uninstallation

[Christian Worm Mortensen]

Hi!

I have made an MSI installer with WiX which installs a service and a
simple UI application.

I see some very weird behaviour with regard to stopping programs
during uninstallation.

If the UI application is running when I uninstall, I get a dialog
where I can quit it. It has a text like "The following applications
should be closed before continuing the install". This seems to work
fine, if I select to close the UI it is closed

However, even though the UI closes I get an error:

  "The setup was únable to automatically close all requested applications (...)"

The funny thing is that if I instead *either* quit the UI application
before uninstall *OR* remove the service from my application, then I
do not get this error.

What is going on? I generated logs for the different cases and grepped
for "REPORT". On these logs there is also only an error in case there
is both a service and a UI application running:

With service, UI running on uninstall:

The UI and the service do not communicate at all. In fact, the UI is
just a default application created by Visual Studio and not modified.

I have an additional question:

I would prefer that the user is not even prompted to close the UI but
that it is just closed automatically during uninstall.

I have tried to use the WiX CloseApplication tag for that. Using that
does not prevent the dialog box above. How do I prevent that dialog so
that CloseApplication can close the UI instead?

Also, if I in the dialog above decide not to close the UI, it does not
seem to be closed by the CloseApplication tag. What have I done wrong?

It was a bit hard finding examples using the CloseDialog and I am very
new to WiX. Here is what I have done:

<InstallExecuteSequence>
  <Custom Action="WixCloseApplications" After="InstallInitialize" />
</InstallExecuteSequence>

<util:CloseApplication Target="[#XXXClientUI]" TerminateProcess="1"
RebootPrompt="no" CloseMessage="yes">
  <![CDATA[REMOVE="ALL" OR UPGRADINGPRODUCTCODE]]>
</util:CloseApplication> -->

Here is a log for an uninstall where I grepped for "close":

This installer did not contain a service, only a UI.
