Tor Browser exits during startup

When reporting a bug, please include as many of these as possible:

The previous post “The TOR browser is unable to be restarted” gave details of the problem but not the solution. Finding out that the torrc file is at fault does not tell me how to fix it.

  • Operating System you are using: Win 11; 25H2 64 bit; 64Gb RAM; 75mbs download

  • Tor Browser version: 15.0.13

  • Tor Browser Security Level: Standard

  • Step by step of how you got to the issue, so we can reproduce it (e.g. I opened the browser, typed a url, clicked on (i) icon, then my browser crashed): Opened TOR, immediately showed message. Restart not possible.

  • About screen says “failed to check for updates”

  • (optional) A screenshot of the problem

  • The Tor log: and where is the log? History shows nothing since nothing was possible.

Version 15.0.14 is out. Here is what I suggest.

Delete the Tor folder on your desktop. Download the new Tor from Tor Project | Download
Check the signature. You probably won’t have the PGP software so right click the executable you downloaded, click properties->Digital signatures
Click the embedded signature from the THE TOR PROJECT, INC. then details. It will say “This digital signature is OK”.
Now click the countersignature from Digicert then details. It will say “This digital signature is OK”.
The download is good. Windows uses it own master certificate list (or whatever it’s called) for validation.
Now install Tor. If there is still a problem, then it is something else.

Could it also be that I install in C:\TOR rather than hidden in Users? I prefer my software to be in C:\Program Files or C:\Program Files (x86) , all in one place!

Possibly. I think to install in the ‘C:’ directory you might need elevated (‘Administrator’) privileges. I’d recommend not running Tor (or most user-space applications) with administrator privileges. Instead install it at some place within your user directories like ‘Desktop’ and so on.

You can install in C:\TOR

I am on another Win11 machine now where I installed the browser in C:\Tor\Tor Browser
I specified c:\tor and it created the sub directory Tor Browser

The link is adjusted when it makes the icon on the desktop to start Tor. I checked the torrc file and it is adjusted also.

To make it run as administrator you need to tell it. So you run in user space.

I also don’t recommend runing anything as admin unless necessary as in sudo on Linux
