There isn't a built-in way to tell the uninstall that the ServiceControl that stops the service is going to shut down your app. That means you'll need to use an uninstall custom action to close down the app - I think WiX has one called CloseApp or something. You'd sequence this before InstallValidate, which is where the in-use situations are detected. You also need a way to tell your service to switch off its monitoring, and use that in a custom action at uninstall time. I've seen this kind of situation before. There are times when these services need to be told to stop their monitoring, such as upgrades, patches, uninstalls, and when to start again. The way I've seen this done is that a registry entry is created/altered, and before the service does whatever it's going to do it checks the registry entry, so in your case the service wouldn't monitor the app. So your uninstall would, in this order.
1. Have an uninstall custom action that writes a "stop monitoring" registry item for the service. 2. A uninstall custom action (CloseApp?) that shuts down your app. InstallValidate finds no files in use and proceeds to stop services, uninstall files etc. 3. Custom action to delete the "stop monitoring" registry item.

Subject: Re: [WiX-users] stop the service before uninstall Forgot to mention: as my application is started by the service it runs in the service context which means they both don't run in the context of the current user, but as "SYSTEM". Also my application doesn't have a window (it's a winmain application but with EntryPointSymbol="mainCRTStartup"). I think the uninstaller checks at the beginning of the uninstalling process which binaries are in use and b/c MyApp.exe is at that point running I get the reboot message. If I could tell the installer to check the files in use at a later point, after the service was stopped (b/c at that point MyApp.exe is also not running anymore) I could get rid of this reboot-message. Can I schedule this check at a later point? Thx, Viv On 3/31/2010 10:25 AM, Viv Coco wrote: >> When, during the uninstall process, are you getting the error?
