To clarify what I mean by “halt my freshly-started background service”, the burn installer is re-entrant when updating. It installs the new stuff, then does something to remove the old bundle from add/remove programs. It’s that latter part that I don’t want to affect anything started by the first half of the bundle update. It sounds like you’re saying that I can change the ordering on that. I’ll look into that more. PS I apologize for no subject on this one.

Depends on the value of your MajorUpgrade/@Schedule attribute. I had an answer ready, but you wrote “halt my freshly-started background service”.

As part of one of my installers, I need to start a background process when it is done copying files. When updating I need to stop the process and restart it again after the files have been updated. When uninstalling, I need to stop the process before the files are removed. Using the sequence below, it appears that when I’m updating to a newer build, the “Stop” call happens after the file copy is attempted. It fails to overwrite the files that were executing. Also, I know that the previous bundle is removed with a -quiet call to the same installer, and I never want that to halt my freshly-started background service. What is the right Before/After and conditions for my scenario?

<InstallExecuteSequence>
                <Custom Action="StartBackgroundService" Before="InstallFinalize">NOT (REMOVE ~= "ALL") AND BUNDLESAYSSTARTBACKGROUNDSERVICE</Custom>
                <Custom Action="StopBackgroundService" After="InstallInitialize">Installed OR (REMOVE ~= "ALL")</Custom>
</InstallExecuteSequence>
