I just bought this and downloaded the install file. When it came to the screen for the serial number there was a number already on it that was different from what was sent in the e-mail. I deleted it and used the sent serial number. I had nero 5 installed and allowed the the install program to automatically uninstall 5. Everything seemed fine except that every time the computer booted the install wizard ran again. I uninstalled 7 and used the nero clean tool but the install wizard still ran at bootup. I used jv powertools regfinder to find nero in the registry and it found over 1200 entries even after using the clean tool. I deleted these and now the install wizard doesn't run at bootup. I'm going to redownload the 7 ultra install file and try again. Any suggestions as to make sure the install works this time? Thanks.
