I am attempting to install and Sony DRU720A DVD dual layer burner. It comes packaged with the Nero 6 vision express 3 software. I have done the following to try and make the installation work: I have uninstalled all my former burning software, including using roxiocleaner. I have used the NERO cleaning tools to clean all the partially installed NERO software off my computer. I have installed and checked a new aspi file to my computer and it is okay and working. I have followed the disabling steps on this website to disable the loaded CD burning Windows XP software. I have error checked my computer. I have the right size of everything. For example, I have 40 G of harddrive available, 512 m of ram ect. I have also tried to install each part of the NERO suite individually. In spite of everything, I continue to get the following error message shortly after installation starts "Error during installation of component “Driverlocker”. I cannot move past this point. Right now, I need to burn CD and at some point a DVD. Thanks to this process, I don’t even have my old CD burning software available. Any help would be greatly appreciated.
