There is also, sometimes, a "Tor windows expert bundle" available on the download page, which would mean you don't need to extract stuff from the Tor Browser directory yourself. I say 'sometimes' because we haven't been super great about keeping it up to date lately. Give it a try and see.
That's what I tried to run, but it shows up a second in the task manager and it's gone. Run as admin, user, with full path, relative path, tor -f bla/bla/torrc, nothing.
Yes, this should be pretty easy to do. Grab the tor.exe out of the tor browser (you might need the whole directory, if there are dll's or something in it). Then grab your torrc and datadirectory from the old relay: https://www.torproject.org/docs/faq#UpgradeOrMove Make sure the torrc points to the new datadirectory, and consider adding a log file: https://www.torproject.org/docs/faq#Logs
And then run "tor -f torrc" from a cmd shell.
I'll give it a try to this now. I'll return with results, who knows, some other may benefit. Running in Linux was a bliss, install, properly make the torrc, run as service. Oh, I also tried adding it as a service in win7, succeeded, but it failed, too.
Good luck!
Thank you, I have a feeing I'll need some.
