I'm doing some Tor tests, and I want to set up a "Single Onion Service". However, when I try to set it, Tor Browser crashes when starts (the exact error is: "Tor exited during startup. This might be due to an error in your torrc file, a bug in Tor or another program on your system, or faulty hardware. Until you fix the underlying problem and restart Tor, Tor Browser will not start.").
According to the Tor manual, I have written the following lines in the torrc file:
HiddenServiceNonAnonymousMode 1
HiddenServiceSingleHopMode 1
However, when I write this and start Tor, Tor crashes. I think I should disable all client-side services, but I do not know how to do it. Can anybody help me?
I attached the current configuration of my torrc file:
# This file was generated by Tor; if you edit it, comments will not be preserved
# The old torrc file was renamed to torrc.orig.1 or similar, and Tor will ignore it
DataDirectory C:\Users\Usuario\Desktop\Tor Browser\Browser\TorBrowser\Data\Tor
GeoIPFile C:\Users\Usuario\Desktop\Tor Browser\Browser\TorBrowser\Data\Tor\geoip
GeoIPv6File C:\Users\Usuario\Desktop\Tor Browser\Browser\TorBrowser\Data\Tor\geoip6
#ServicioOculto:
HiddenServiceNonAnonymousMode 1
HiddenServiceSingleHopMode 1
HiddenServiceDir C:\Ser_Oc
HiddenServicePort 80 127.0.0.1:441
If I delete the HiddenServiceNonAnonymousMode 1 and HiddenServiceSingleHopMode 1 lines, or I "disable" them writtingHiddenServiceNonAnonymousMode 0 and HiddenServiceSingleHopMode 0, Tor starts correctly and my hidden service also works correctly.
I am using Windows 10 and Tor Browser 6.5.2
(Sorry for my English; English is not my native language).
============================================================
UPGRADE
Well, I'm going to tell you several things (although I have not been able to solve my problem).
First: Through Tor Browser (and running Tor Browser with administrator privileges), I changed the address ofHiddenServiceDirectory to C:\Users\Usuario\Desktop\Ser_Oc. However, I had the same problem: everything works fine, but when I add to the file torrc the lines HiddenServiceNonAnonymousMode 1 and HiddenServiceSingleHopMode 1, Tor Browser does not start, and displays the following error window: "Tor exited during startup. This might be due to an error in your torrc file, a bug in Tor or another program on your system, or faulty hardware. Until you fix the underlying problem and restart Tor, Tor Browser will not start".
I leave here the configuration of the file "torrc" when I did this new test:
# This file was generated by Tor; if you edit it, comments will not be preserved
# The old torrc file was renamed to torrc.orig.1 or similar, and Tor will ignore it
DataDirectory C:\Users\Usuario\Desktop\Tor Browser\Browser\TorBrowser\Data\Tor
GeoIPFile C:\Users\Usuario\Desktop\Tor Browser\Browser\TorBrowser\Data\Tor\geoip
GeoIPv6File C:\Users\Usuario\Desktop\Tor Browser\Browser\TorBrowser\Data\Tor\geoip6

Second: When I start Expert Bundle (also with administrator privileges), the command-line interpreter shows the following:

However, if I put the torrc file (with the configuration I have previously set) in C:\Users\Usuario\AppData\Roaming\tor directory, Expert Bundle does not start: the command-line interpreter where Tor is loading closes after a few seconds. It shows no error.
Update 2
All right, everything is going well! Firstly, I have managed to start Expert Bundle and configure my service "Single Onion Service". The problem was this: I used the torrc file from Tor Browser, so the file torrc had the directories misconfigured!
Now, I have the following doubt. In effect, I have configured the hidden service "Single Onion Service". In fact, the Expert Bundle command interpreter says that the hidden service has been configured correctly:

On the other hand, in the HiddenServiceDir directory (C:\Users\Usuario\Desktop\lkfajsdflkasjf), I can see three files: hostname, private_key AND onion_service_non_anonymous. So, I think everything is well configured.
However, when I access my to my hidden service from Tor Browser, and I see the circuit, I see six relays yet! Three relay which correspond to my Tor Browser, and then three relays which appear as "(relay)". My question is: if my hidden service is configured in "Single Onion Service" mode, why do these three relays appear? That is, theoretically my hidden service would have to connect directly to the rendezvous point, right? So, why do these three relays appear?
I put here the current configuration of my torrc file (maybe it can be useful):
# This file was generated by Tor; if you edit it, comments will not be preserved
# The old torrc file was renamed to torrc.orig.1 or similar, and Tor will ignore it
