Downloading and installing a JNLP program
When you click on a link to a program, your browser should start to download the program automatically. If it doesn't, right click the link and choose the 'Save As' option. Choose, or or take note of, where the program is saved. Once the download is complete, you can move this program to any location that you want to.
Running a JNLP program
Once the program is installed, running it should be as easy as double-clicking the icon of the program. However, if the program does not start, you may need to install Java. Go to http://java.com and click the giant 'download now' link. Java should begin to download and install automatically. If not, consult the Java website for instructions. After that, the PoPS programs will work.
