I am using tor browser on windows 10 pro, and recently I can not use it. when I start the program, I receive following message:

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

best regards, Farshid

    It sounds like something has gone wrong with the installation, something has changed permissions on your filesystem. It might be worthwhile simply removing it and reinstalling it. – cacahuatl Aug 16 '17 at 0:58

It could most likely be your anti-virus that's causing this. Go to the anti-virus application you have installed and try turning off the "file protection" option.

On Bitdefender, this is the Safe Files option within Protection Features.


My Tor-Browser is installed in C:\ProgramData\chocolatey\lib\tor-browser\tools\tor-browser\Browser\firefox.exe

What worked for me is to give your Windows User write ("change") access to C:\ProgramData\chocolatey\lib\tor-browser\tools\tor-browser\Browser\TorBrowser\Data\Browser


I know this is a very old question. But for future reference, the easiest way, I believe is to run the program as administrator. You can make this a default setting from the properties>advanced section.
