Simply follow the prompts for language and the operating system version your PC is running on. Place a check in "Download the full version of Adobe Reader." No other software is necessary, so you may decline the other options presented.
 
The download is fairly large (15.9MB or larger at this time depending on options selected), so plan accordingly. Once you have saved the installation file to your PC, right-click the file and select Open. This will begin installation of the Adobe Reader software. Follow the prompts to complete the software installation.
