First: I've never used Tor Browser or similar applications, so please forgive my noobness.

I'm pretty sure I've done everything correctly, but I still can't seem to connect. I've downloaded the newest version of Tor.

I've disabled firewall and my free Avast anti-virus. At least, I think I did. I'm not too sure how to check on that.

When I open Tor Browser, the small window opens while "trying to connect." However, I always get an error message "Could not connect to Tor control port." I'm not sure what I'm missing.

I'm running Win 7.

That is a local problem which is probably related to your firewall. The control ports which need to be tunneled through the firewall are 9150 and 9151.

  1. at https://trac.torproject.org/projects/tor/ticket/11023 user "badon" says

    I copied my portable Tor Browser Bundle to another drive, and it worked!

    you could give that a try, too

  2. see if the problem occurs in Safe Mode with Networking (press F8 while starting to access)

  3. try the TBB on a friend's computer to see if you have the same problem

  4. follow the steps at https://trac.torproject.org/projects/tor/ticket/11776. (f.ex. by uninstalling your AV software)

  5. check your firewall

  6. There are directions on changing your ports from 9150/9151 to others at https://trac.torproject.org/projects/tor/ticket/13150

  7. download TAILS to a USB stick and boot from it to use Tor.

  • I apologize, but have no idea what the above solutions are. I've turned my firewall off, so I dunno how much answers 1 and 2 helps. Am I missing another way to disable windows 7 firewall? I've done number 3...

  • Is there a site which has some basic information on this stuff? I literally don't know half the things that are talked about here. I've completely disabled my windows firewall and deleted my antivirus, so I don't know what the holdup is. I have no idea how to do that port stuff or find logs or any of that. I'm a noob without this deep computer knowledge who wants to simply browse online without the government or other no-gooders gathering up my information.

    @adcindy Just as a double check, you may want to open the Windows Task Manager -> Processes tab. I have noticed that tor.exe sometimes is running when you don't expect it to be. If it is running, highlight tor.exe with the mouse and then click the "End Process" button before attempting to restart the TOR browser. Commented Oct 31, 2015 at 12:21
