I encountered the Access Denied problem when migrating from XP to Vista, and have found a few ways around the problem. The problem occurs when utorrent cannot access the file, my Vista user accound is not administrator and the file could not be written by user, therefore the error occurred. The way to get around it is to change file permissions to include everyone like shitface said. Another way is to run utorrent as administrator (this just worked). Running utorrent as administrator presents a problem though when trying to add a torrent by opening a torrent file from windows, it tries to add the torrent to the administrator running utorrent, but cannot access it because i am only a user, therefore presents the message 'utorrent is running but not responding' I have to go to utorrent and manually add the torrents from the file menu, this is not a good thing. Could this issue be fixed? Cheers edit: using 1.7.7, sorry about that.
