I was getting this error, after installation with Chocolatey, when trying to start Tor Browser:
Tor Browser does not have permission to access the profile.
I tried changing permissions on
C:\ProgramData\chocolatey\lib\tor-browser\tools\tor-browser\Browser\ and similar, as recommended here and there, but it still didn't work.
What finally did it was giving my user Write and Modify permissions to
C:\Program Files\Tor Browser\Browser (as well as R&E, List, Read). (Even though I was already in a group (Administrators) that had such permissions.)
This is in Sep. 2020, with version 9.5.4.
