Vista iTunes 18.104.22.168 Solution
If you're running Vista you might have a problem installing the new update for iTunes (which oddly enough should help functionality in Vista.) You might, as I did, run into an error message involving VBScript. If so, Stephen at www.covidimus.net has a great solution on his blog. By the date of his posting, I can tell that he wrote it during the early days of Vista, but I found it helpful when installing this latest iTunes update last night.
