Hi,

I like your installer, and I have just few suggestions.

Maybe I suggested earlier, but it seems, that all versions of thinBASIC are visible in Add/Remove programs as just "thinbasic". Maybe version number added could be more informative ( I'v now at least 8 "thinbasic"s there )

I'm not much experienced in coding installation using Inno setup, but I think installer could check the necessity of "Key activation"

"Place thinAir shortcut on desktop" and "View latest changes" could be added to the last frame of installation

Thanks,
Psch
