Dotproject.org reports Microsoft latest add-on for Windows XP, Plus! Digital Media Edition, has fallen foul of Windows Product Activation. Numerous purchasers are finding it impossible to install, and are being confronted by the comforting message "Plus! Digital Media Edition uses Microsoft Product Activation to help prevent software piracy. Please have an administrator run Plus! Digital Media Edition on this machine and go through the Microsoft Plus! Product Activation Wizard. Once that is complete, you will be able to run Plus! Digital Media Edition normally." Except, er, no you won't.
