And what if, for example, version 7 comes out in a year and you give your software a different name, then it costs 12 dollars again?
I mean, it's ok that you want or need to make money with your software, but then you should communicate that better beforehand, right? As you can see here in the forum, not all buyers seem to realize that an update of the Windows version from 5 to 6 costs money again. In my opinion it's not enough to simply say that the two versions 5 and 6 are two completely different programs.
