You can always download latest version of Adobe Reader 8.0 from
Adobe website. However, the setup file that you downloaded is actually a download manager which has a small download size. The Adobe download manager later will be launched for configuration options and then download the actual installer setup files for Adobe Reader once you have finished select the components you want. This miniature installer is not useful if you want to install Adobe Reader in other computer while offline or for backup or installation file. For offline installation and other purposes, it’s best to download the full installer instead, which can be used to setup and install Acrobat Reader 8 even when you’re not connected to Internet. The direct download links to various localized language editions of Adobe Acrobat Reader 8 is listed below.
