[wix-users] Elevated CA before GUI?

[Persson, Magnus (SE-TLX)]

I am fairly new to WiX and have not yet looked at the util schema. 
Perhaps that will work.
It would be nicer to stop our services and kill our processes from WiX 
instead of asking the user to do it manually and restart the msi/setup-file.

I see there is a 'TerminateProcess' attribute to the CloseApplication 
util. As long as this can be called before the file copy process starts 
it will be fine.

The RestartResource sound like it will restart the service. What I need 
is to stop the service. Can this be done?

Regards,
Magnus
