So here's an installation sequence that might work in that case:
(1) Open the installer.
(2) During installation, when asked where to install, DO NOT install in the default directory that is suggested. Instead, choose a location within your Documents folder.
(3) After installation, make sure that both the new Nero folder and the 2.0 folder are not read-only. To do that, right-click on the folder and choose "Properties." Then toggle the "read-only" button to OFF. Make sure that is done for both the NERO folder and the 2.0 folder within the Nero folder.
(4) Now go to the folder [Install directory] \ Nero \ 2.0 \ nero \ client \ scripts
(5) Within that directory, replace the file tutorial.cs.dso with the newly supplied tutorial.cs.dso.
