Hi Edel, " 1 - Can I install it in such a way that it doesn't activate when I switch on the PC as I don't have sole use of the computer. " Yes, of course you can. Supernova is set to load up on startup after its installed. If you go into the "start menu, programs menu, then arrow down to the startup window". Right arrow in here and you will see there is a supernova icon. Just press the application key on this icon and choose delete. Answer yes to have it deleted and then restart the computer. Now supernova will not automatically start in future. " 2 - How compatible is supernova with the internet now. My past experience with my old version was not good. Always crashing... " As far as I know supernova from versions 6.0 onwards is pretty good but as I am not a supernova user I am not sure. Perhaps one of the I.T trainers could answer this. " 3 - I have a database installed on the PC which has many modules already enlarged for my benefit. Will it be compatible with that programme or will I need to turn it off? " I don't see why there should be any need to turn anything off, just see how it goes for the moment okay. Hope this is of some help Edel.
