Is the best way to update a running Service by using another service? [C#]

[Shaitan00]

I need to find a reliable way to update a running Windows Service (Service.exe).

The service is run under the LocalSystem account whereas the logged-in user is in a non-admin User account.

 

My current solution would be as follows:

- The Service.exe checks for updates (files) regularily

- When an update it found it starts another service (Launcher.exe) that would stop the Service.exe, copy over the files, restart Service.exe, then stop itself

 

After doing some online-reading and from some of my previous forum posts I beleive this would be the appropriate solution - but before I go ahead I wanted to check with all the guru's and see if I am forgetting something important or if there is a better way.

 

I did read-up on some method of self-updating (loading & unloading assemblies, etc...) but it just seemed very unsure and I need this to be as robust as possible - if it fails it means someone needs to manually intervene.

 

Any help or hints would be much appreciated.

Thanks,

Personally I can't see any other way realistically to update a service automatically without user intervention, the only issue you may need to worry about is if the launcher.exe needs updating :D
