From the msdn topic on sequencing custom actions:
As in the case of standard actions,
custom actions that are scheduled in
the InstallUISequence or
AdminUISequence run only if the
internal user interface is set to the
full level.
So I guess your custom action is scheduled in a UI sequence, not in InstallExecuteSequence
. Try scheduling your custom action in the InstallExecuteSequence
like this:
<InstallExecuteSequence>
<Custom Action='LaunchApplication' After='InstallFiles'/>
</InstallExecuteSequence>
where "LaunchApplication" should be replaced by the Id
of your CustomAction
element.
edit: I looked at the instructions that you followed, and I don't see the custom action for launching the application being scheduled in any sequence. It is only triggered from a UI action (clicking the Finish button). This explains why it is never executed during a silent install.
edit: full sample (it's a bit sloppy as it also tries to execute the custom action on uninstall, repair etc. but for some reason I couldn't get the "NOT Installed" condition to work)
