Manual install method for Windows:
 - The download/unpack process is automatized on Windows, but if it's fails for any reasons follow the next steps.
 - Download Expert Bundle from https://www.torproject.org/download/download.html (tor-win32-*.zip)
 - Copy everything from the archive's `Tor` directory `tools\tor` and the files from `Data\Tor` to `tools\tor\data` (you need to create it)
 - You should get directory structure similar to this:
   tools\tor:
    │ libeay32.dll
    │ libevent-2-0-5.dll
    │ libevent_core-2-0-5.dll
    │ libevent_extra-2-0-5.dll
    │ libgcc_s_sjlj-1.dll
    │ libssp-0.dll
    │ manual_install.txt
    │ ssleay32.dll
    │ start.cmd
    │ tor.exe
    │ torrc
    │ zlib1.dll

   tools\tor\data:
    │ geoip
    │ geoip6
 - Start ZeroNet, it will run and use the tools\tor\tor.exe file

For other OS:
