I found a way to register and activate Norton AV 2005 silently. I figured I would share it. IMPORTANT: You first have to copy symlcrst.dll from a computer with Norton AV 2005 already installed and activated. It is located in the %systemdrive%\Program Files\Common Files\Symantec Shared\ccpd-lc\ directory. Just copy the file to your xpcd\$oem$\$1\install\applications\NortonAntivirus2005 directory Put this in your start.cmd: ------------------------------ ECHO. ECHO Registering and Activating Norton Anti-Virus 2005 ECHO Please wait... COPY "%systemdrive%\appz\NortonAntiVirus2005\symlcrst.dll" "%systemdrive%\Program Files\Common Files\Symantec Shared\ccpd-lc\symlcrst.dll" REGEDIT /S %SYSTEMDRIVE%\appz\NortonAntiVirus2005\NAVSETUP.reg ECHO. ECHO Installing Norton Anti-Virus 2005 ECHO Please wait... start /wait %SYSTEMDRIVE%\appz\NortonAntiVirus2005\NAVSETUP.exe "/qn /noreboot REBOOT=ReallySuppress" Your NAVSETUP.reg file should look like this: --------------------------------------------------- Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\CCPD-LC\KStore\00000082\0000000f\0000001b] "Key"="PUT KEY HERE WITH NO DASHES" Hope this helps some of you out. It took me a while to figure out. B)
