When I ran Windows Installer Cleaner; I had no iTunes enry. Howerver my top entry had (All Users)
http://7.0.2.16. I'm not sure this is the entry to remove. Is it??
A month late, but yes 7.0.2.16 is an iTunes version number. So that would be (would have been?) the previous version of iTunes the installer was complaining about.
When my memory fails me as to what is an iTunes version number and what is not, I usually try a search of the iTunes for Windows category with restrict by date set to all. Usually, someone will have been accidentally kind enough to have cited all four numbers for the iTunes version.
