NSIS (Nullsoft Installation System) script. The installation script is saved in unXmit’s installation target directory. The install script performs these functions:

·         Welcome Screen

·         Choosing Components for installation: unXmit and Java’s JRE

·         Choosing a different target directory. I normally install into C:\Program Files\unxmit ; however, when I am testing, I use a directory in my home directory. It does not make any difference; the code executes wherever you install unxmit..

·         Installation Progress presenting at least one, and maybe two progress bars. The first progress bar represents unXmit’s installation progress; the second represents Java’s JRE installation, and is displayed if JRE installation is necessary.
