All applications on this page are written i Visual Basic. If you have ever installed a Visual Basic application before or have Visual Studio installed you have all that you need to just run the exe file.
So, in comment for all these downloads is that you should at first download the .exe file and see if it works as it is. If not you can download the full setup file, unzip it and install it.
You can also download and install the Visual Basic runtime from www.microsoft.com
