I have just installed Tor Browser package (Windows), using my admin account (installation failed with a normal account due to insufficient privileges. I am able to start the Tor browser ok with the admin account. However, when I switch to my regular non admin account and try to start the Tor browser, I get that error message that says Firefox is already running. I have attempted to fix this particular problem from Mozilla help, but they just don't work. (There is a firefox profile lock file that needs to be deleted; I did this and it made no difference). So can you only run Tor browser from the same account that you install it in? If this is the case, then I'll need to un-install and then re-run the installer from an elevated command prompt, however, I tried to un-install Tor-Broswer, but I can't find an un-installer, and the Tor Browser doesn't appear in the application install list (appwiz.cpl).
Please assist if you can, thanks.
