I explained that there was difference between Vista and previous OS versions in
ServiceControl behavior, and also that there may be a bug in Vista and later
when you have more than one ServiceControl action. However you didn't say what
OS you're actually using, or whether you have more than one ServiceControl
entry.
Is it an upgrade? I know you refer to uninstall, but there's also a mention of
install/upgrade. If it is an upgrade, where is RemoveExistingProducts
sequenced?
So being nitpicky, you're repeating the question without supplying any more
information, so the answer to "Are you saying that I don't really have a way to
do this? I mean the user will have to either stop manually the service before
an uninstall/upgrade or to reboot the machine after an uninstall/upgrade?"
depends on the OS you're using, and if you have more than one ServiceControl
entry.
a) Doing the uninstall while taking a log might be useful (msiexec /x
{productcode} /l*vx <path to a text log file> ) because the list of files in
use should give you a better picture of the files involved (which may not be
simply your service exe) and whether the in-use is detected at InstallValidate
time or at file removal time (see b and c).
b) Sloppy programming can be an issue if there are handles open anywhere that
refer to the service or the process being watched. Windows can't uninstall a
service if there are handles open to it.
c) If ServiceControl isn't set to "wait" the service may not have actually shut
down by the time Windows tries to delete it, a timing race. Or If the service
shuts down but the process lingers then the process is still there at file
removal time requiring a reboot to delete.

Subject: Re: [WiX-users] stop the service before uninstall
Hi guys,
I really don't want to be pushy but I need to find a solution for this:
besides my application I also install a service that is babysitting my
application, eg: restarts it when it crashes or whatever. When the
product is uninstalled I get the message: "The setup must update files
or services that cannot be updated while the system is running. If you
choose to continue, a reboot will be required to complete the setup."
even though I specify that the service should be stopped when
uninstalling (and the service will take care to also stop my application).
[code]
<ServiceControl Id='MyServiceControl' Name='MyServiceForTest'
Start='install' Stop='uninstall' Remove='uninstall'/>
[/code]
If I manually stop the service before uninstalling everything works fine.
How can I solve this problem? I can't really ask the users to manually
stop the service before uninstalling or to reboot the machine on every
upgrade. How can I force the shutting down of the service?
Thx,
Viv ;)
