Possibilities:1. the CD/media you are installing from has corrupt files. Obtain new installation media and try again.

  1. A previous installation attempt left corrupt files on your machine. Uninstall previous versions of Notes and delete all related files/folders. (Back them up first if desired.) Then attempt the installation again.
