Ahhh! Finally success has found me. Must be a mistake. lol I found that using a "msi" file does not like to have a space in the name of the "msi" file name. Out of the box the installer for Symantec 9.0 CE is named "Symantec Ativirus.msi. Simply deleting the space in the name was part of the answer. (I then chose a shorter name as I am a lousy typist (lazy). Then to use the proper syntax was also helpful. Hehehee. Last but not least this is what was used for silent install on my Unattended_Xp cd for my install of SAV, REG ADD %KEY%\005 /VE /D "Sav" /f REG ADD %KEY%\005 /V 1 /D "%systemdrive%\Install\Sav\sav9.msi /passive RUNLIVEUPDATE=0 REBOOT=REALLYSUPPRESS" /f Thanks go to Prathapml, Smiley, Yzowl, and Durex for your guidance, speedy replies, enthusiasm, and finally the re-inforcement to complete the task at hand. I wish I had joined this forum sooner. Next project is to fill the little bit of space left on the cd (about 16 megs) and add additional reg tweaks. There are some settings for the desktop etc., I would like to integrate into the uA_CD. Respectfully, Nova
