I notice you have posted this error on a number of other forums with little success. The clue is in the message "error: access is denied". Try running the app with elevated privileges (right click the app>more>run as administrator).
If that doesnt work try other steps you have already tried but when possible "run as administrator".
If this fails check the permissions on the temp file.
The temp file will be recreated if you delete it as its required by the app and if missing it will recreate it.
Hope this helps.
