Let’s take a look at the description of the process involved regarding each of the solutions listed.

Before continuing with the solutions below, you should make sure that your Windows computer clock is set to the correct date and time. Additionally, only one instance of TOR can run at a time, so check if TOR is already running in Task Manager. If in doubt, you can simply restart the computer. And if your system just resumed from hibernation or sleep mode, relaunch the TOR browser or restart the computer.

1]Assign Full Control permission to TOR browser folder

You may receive the following error message after installing TOR and trying to launch the browser;

The Tor browser does not have permission to access the profile. Please adjust your file system permissions and try again.

In this situation, you can resolve this issue by granting Full Control permission to the TOR browser folder, and then relaunch the browser. By default, TOR is installed in the following location on your local disk:

C:Program FilesTor BrowserBrowser

If that didn’t work for you, try the next solution.

2]Disable security software

Security software (especially from third-party vendors) running on your Windows PC may falsely flag the TOR browser, preventing it from opening or functioning properly. If so, you will need to whitelist TOR or disable your security software.

You can temporarily disable Microsoft Defender, if this is the security software you are running on your system. Also make sure TOR is allowed through Windows Firewall.

If you have installed third-party security software, disabling the program largely depends on the security software – see the instruction manual. Usually, to turn off your antivirus software, locate its icon in the notification area or in the system tray of the taskbar (usually in the lower right corner of the desktop). Right click on the icon and choose the option to disable or quit the program.

3]Check the internet connection

This solution requires you to make sure that you are not having any internet connectivity issues on your Windows 11/10 computer. You can also try restarting your internet device (modem / router) and see if that helps.

4]Obtain a new IP address

The TOR browser is designed to work very distinctly by assigning a new IP address different from the one assigned to your computer by your Internet service provider. If there is a problem with the IP address, you may experience these problems. In this case, you can go to the TOR project site at to see which IP you have currently been assigned. On the site, to obtain a new IP address, all you have to do is click on your browser’s wand.

5]Kill the Firefox process

The TOR browser has the DNA of Firefox. So in this case, you may need to kill the Firefox process before TOR can run on your Windows 11/10 computer. Additionally, you can also restart the file explorer process.

6]Delete the parent.lock file

To delete the parent.lock file on your Windows PC, follow these steps:

C:UsersUserNameDesktopTor BrowserBrowserTorBrowserDataBrowserprofile.default
  • At the location, scroll down and locate the parent.lock to file.
  • Select the file and press WIPE OFF key on your keyboard. You can also right click on the file and select Wipe off from the context menu.
  • Exit the file explorer.

See if the TOR browser issue is resolved. Otherwise, try the next solution.

7]Uninstall and reinstall the TOR browser

This solution requires you to uninstall or remove TOR browser as follows:

  • Locate your Tor browser folder or application.
  • The default location is the desktop.
  • Delete the Tor browser folder or application.
  • Empty your trash.

That’s it! TOR is uninstalled! No need to use Control Panel in this case.

Now restart the PC and then download and reinstall the latest browser version on your Windows 11/10 PC.

8]Use another privacy browser

This is more of a workaround than a solution. This implies that you are using a different privacy browser.

9]Contact your ISP

It is possible that your ISP has blocked the TOR browser – ISPs collect data and monitor traffic entering and leaving your Windows system for various reasons. and TOR browser due to its privacy settings usually blocks this traffic. In this case, you can contact your ISP to make sure TOR is not blocked for you.

10]Contact the TOR support team

If your ISP has not blocked TOR, and you have also exhausted all other options, but the problem persists, you can find your TOR log, copy and paste the logs into Notepad, so you can browse and analyze the log results yourself or send it to the TOR support team to help diagnose the problem and possibly offer a solution.

To view the TOR logs, follow these steps

View TOR Logs

  • Open the TOR browser.
  • Click on the hamburger menu (three vertical lines) in the upper right corner of the browser.
  • To select Options.
  • Click on Tor in the left navigation pane.
  • In the right pane, scroll down and click Look at the connections.
  • Click on the Copy Tor Log to Clipboard.
  • Now open Notepad and paste the content into the text editor.

You can now sift through the data to determine what problem the browser is having.

How to fix TOR that quit unexpectedly?

If you get the error message saying TOR closed unexpectedly, it is most likely due to a bug in the TOR browser itself, another program on your system, or bad hardware.
