1. Yes, of course. But user can pay only after registration (it is one-step procedure). 2. Yes, it is possible.
Thank you again for helping Alex. Is this an automated service ie do users recieve their product + serial after they have paid, so that hundreds can do it at the same time? I am very interested in this software, but I do need the download feature to work.
Which payment processor are you going to use? You could just stick with SWREG.org for first time, then you just don't need any special software.
