I bought the product on "AMAZON" no perfect problem. All service on the Internet asks tehniques NERO QUEST: -it must uninstall all previous configurations? REP: Not all versions will enssemble. Unless the version TRIAL NERO 9 follow the directions below. What I did !! For the installation of NERO 9 with "disc system" after 15 tests the installation is done, but can not open "Nero Vision" Help Request to the same service by email (6 in all) no answers. So I phoned scupuleusement by following the instructions sent by mail, and by downloading NERO 9 with the ID number written on the purchased DVD. If you want all the cleaning protocol of your drive before installation, contact me via an "amazon". Good luck.
