Your method does not work, because activation status is stored not only in registry but in files "PowerDVD8.sim" and "CLAud.sim". You should replace original files with the activated ones. Otherwise, you will be asked to activate the program at the first start. PS: Sorry for my poor english;)

Add this line to your script just before invoking nero installer: reg delete "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager" /v PendingFileRenameOperations /f This will solve your problem.
