Just as Sir Richard who posted his problem 4th Feb, 2009, I also have a medion pc with Vista as o/s. I received on my pc that I must upgrade my software and I went ahead and said yes. After I upgraded it I found that I cannot use my Nero8 Express Essentials that came preinstalled with my pc. I have a back up application disc and I install Nero8 via this but once the installation is complete errors pop up, such as side by side configuration is incorrect, unable to register, error code 2147010895, error 14001 and these errors pop up against all the Nero essentials. What am I doing wrong, why can't I reinstall this program? By the way I am new at this so I need an idiot proof solution. Many thanks.....................jj by the way I emailed Nero without any responce....................
