An excellent new Reader,
, which is a "Small, Fast, Clean, and FREE PDF Reader for Everyday Use" has become available.
After the FoxitReader zip file is downloaded into a folder where you can find it or to desktop, unzip it for use. Make sure to set it to be your default reader. You may have to uninstall Adobe Acrobat to get it to be default.
If you prefer, you may obtain Adobe Acrobat Reader
which has become quite bloated and does not run well on older systems.
