c# - Kill windows service forcefully in WIX

Question

I have windows service which will get installed as part of wix installation . Problem is that, currently service is in production and it is not responding to stop due to some poorly written code in service OnStop method .

So next time when the user tries to install upgraded version installation will fail because service will never stop when wix tries to stop the service .

Is there any way in which i come to know if wix is taking too much time to uninstall and i can kill the process if i get that notification ?

Also, is there any way i can kill process based on product version ?

Thanks

Answer 1

I shouldn't answer this since it has been ages since I have dealt with stuff like this, but what the heck, let's try.

1. CloseApplication Element: Maybe I would just try WiX's CloseApplication Element first. I doubt it will work for a service, but this is the most convenient approach I can think of off the top of my head.
2. Sysinternals PsKill: Mark Russinovich's PsKill would be worth a try. I think his tools are redistributable so you can include them in your setup, and they are always good. You have to invoke it from an elevated, deferred mode custom action - which is alway more involved than using a built-in WiX construct.
3. Taskkill: There is also the built-in Taskkill - which I have never used. Suggested use with the sc tool.

I want to emphasize that I haven't actually tested these tools for killing services, and I don't have time to do so right now. There could be issues with the sequencing whereby StopServices could be scheduled before the CloseApplication custom action from WiX is scheduled to run. Please check the InstallExecuteSequence using Orca (towards bottom) after compilation to see whether this is the case.
