Here's what I get in a pop-up window titled Windows Service Start Failure:
Windows Service Start Failure
Cannot start service from the command line or a debugger. A Windows Service must first be installed (using installutil.exe) and then started with the ServerExplorer, Windows Services Administrative tool or the NET START command.
This is from an administrator command prompt with the service stopped, command was nrecord.exe run in the program files/npvr directory.
FWIW, here's what's in Event Viewer for this start attempt:
- <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
<Provider Name="NPVR Recording Service" />
<TimeCreated SystemTime="2012-05-09T01:58:22.000000000Z" />
<Data>Service cannot be started. The service process could not connect to the service controller</Data>
