What is it?
Well, it's just a launcher for Microsoft's Calculator with a splash screen. :P
The splash isn't that great right not, I will spend more time on it for the next release, when I cahnge the icon for the self extractor, but bascially, it's just a simple little launcher so you8 have quick and east access to the Calculator from your portable apps menu. I will be happy to give a shot at an actual calculator to make portable, is some people could give me links to some open-source calculators they have found. Thanks!
Edit: Development of this launcher (Although none is needed) will be discontinued as I have found and created a portable version of TTCalc, a better, more functional calculator. The thread can be found here.
