After the install and activation a wizard should be very useful for the non advanced users to configure the program with some easy questions, like setting up an Identity Safe profile right after the install, creating the default backup-set and the timing of it, setting the firewall, some AV options (office scan, early load), antispam integration, etc. This could be done on a few pages, abd most of the settings would be configured this way.
For the advanced users this wizard should be not necessary, so a 'No, thank you, I will configure the program myself' option should be there as well.
By every function, a little explanation should be there for the users, what that option can do.
