Lois, What kind of key do you have?
if you have an OEM key you cannot use this switch
/sn=xxxx-xxxx-xxxx-xxxx-xxxx-xxxx and you should put your key in a .reg file
CODE
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Ahead\Nero - Burning Rom\Info]
"User"="Something"
"Company"="Something"
"Serial6"="xxxx-xxxx-xxxx-xxxx-xxxx-xxxx"
and call this file before your installation of nero (example with RunOnceEx.cmd)
CODE
REG ADD %KEY%\001 /VE /D "Nero Burning ROM 6.6.0.0" /f
REG ADD %KEY%\001 /V 1 /D "REGEDIT /S %systemdrive%\install\Applications\Nero\register.reg" /f
REG ADD %KEY%\001 /V 2 /D "%systemdrive%\install\Applications\Nero\nero.exe /silent /noreboot /no_ui" /f
