If you want to scrobble your local files, you will have to have the Winamp media
library installed. (Most people use this anyways.) Otherwise you can configure AWAAS
to not scrobble local files at all.
The Windows Scripting Host must be active. (If you don't know what that is, don't
worry, then it is most likely active.)
MSXML version 4 must be installed (this is also usually already installed on
any XP or Vista computer). If not, then it won't hurt to install it. You can download it
Internet Explorer 6 or higher. AWAAS uses it to display user dialogs or last.fm radio information.
