To download the three system install files from the Primary User Area, select the version directory (navigate to the directory), and you will see these three files:

Right-click each file, and from the menu select  "Download." You can then select a location on your system to store the files, such as your desktop or other designated subdirectory.

The Setup999.exe is a large file and will take some time to download, the two other files are small and will download quickly.

To install, execute the Setup999.exe file and follow the direction of the installer program.

The procedure for download is similar in the Secondary User Area.
