Now that the
file has downloaded, look for it on your desktop. The file name should be
something like 'ar500enu'.
If you are
using Windows, the file will end in '.exe' (Windows may hide this from you).
If you are on a
Macintosh, the file will end in either '.sit' or '.bin'. Double click on this
file to extract it. This will create another file that you will need in the
next step.
Double click on
the file from the last step, this will start the installer. Say 'Yes' to any
questions it asks, the default location is fine. The installer may ask you to
restart your computer. This is fine, once you are done, you are ready to view
and print PDF files!
