windows service & updating c# console app

I have a windows service that executes a console app every hour a开发者_如何学Gond it's running with no problems. I didn't set this up though, and I'm not familiar with windows services at all.

Today I had to update the console app, so I presumed that if I just copied the exe file back into the folder were it was called from the windows service after I modified it it would be fine. But it looks like it stopped working.

I ran the console app mannually from the command prompt and it works fine though.

Any ideas on why this could have stopped working?

Thanks

first try to stop/start your service, then try to uninstall and install your service again

you can do the first thing in administrative tools/services install/uninstall with installUtil
