I received error messages in uTorrent after switching from Windows XP to Windows 7. All uTorrent downloads were showing Error: Access is denied after a few seconds. The temporary solution was to run uTorrent in Windows XP SP3 compatibility mode. Several users commented in the thread stating that they did not experience this error messages in Windows 7.
Further observation revealed that only old torrents were showing that error message while new torrents added after the installation of the Windows 7 operating system where not throwing the error and downloading just as expected even if compatibility mode was disabled. The solution to the problem was therefore an access problem of the new Windows 7 user account. More precisely a write access problem.
It was thankfully very easy to fix. A right-click on a temporary file or folder in the uTorrent cache folder and the selection of Properties opened a window with configuration possibilities. The Security tab at the top of the window led to a page with access permissions for the selected data. It displayed the access rights for various system users including the system administrator, the content owner (that's the Windows XP user in this case) and the currently logged in user.
This can be easily changed by clicking on the Edit link to edit permissions for specific users of the computer system. All it takes is to select the current user in that new window and add write access permissions for that user to the list of rights. Once that is done the torrents will download just fine without errors.
The same write problem exists for other files that have been created in the previous operating system. If you are encountering write problems you simply need to add the write permission for the logged in user to write those files (for instance if you want to overwrite them with a newer version).
