I am a newbie. There are some questions, anybody could help me? 1. I want to an unattend aplication install by runonceex, is there any method I can choose which program to be installed from a list? 2. I will install norton antiviurs but I must upgrade the software and restart the PC serveral times. Is there any method I can upgrade the norton software automatically? 3. Could I install some software without entering the serial No? When the user use the software firstime, then they can enter the serial No by themselves. Thank you very much.
