    Getting Acrobat Reader onto your computer is a two-step process:

    1. Download the Acrobat Reader Installer.

    2. Run the installer to install Acrobat Reader. Be sure to allow enough time for both steps to complete.

    Set your browser to enable JavaScript. If you don't know how to set this browser preference, see the topic “Make sure JavaScript is enabled” for either Windows or Mac OS.

    From time to time, your antivirus software may incorrectly identify the Acrobat Reader installer as malware. False error reports include “TrojWare.Win32.Trojan.Agent.Gen,” “Trojan/JmGeneric.bcy,” and “Suspicious.” Users also report “Failed to Initialize” errors and having the installer quarantined.

    Antivirus software vendors and service providers actively update their software so that the Acrobat Reader installer is recognized as legitimate. Ensure that your antivirus software is up to date.

    Certain conditions on your computer, such as security settings or browser cookies, can prevent the Acrobat Reader Installer from downloading. Often, the easiest way to resolve an unsuccessful download is to try the download again using a different browser. Try any of the following browsers that you are not already using:

    • Mozilla Firefox 
    • Microsoft Internet Explorer 
    • Apple Safari 
    • Google Chrome

    If you don't see a confirmation window indicating Acrobat Reader was downloaded and installed, look to see if your browser has opened a downloads window. Some browsers are set to open a separate window for downloads, but it’s possible that other open applications or windows are hiding the download window. If you find the downloads window, double-click the Reader .exe file to continue the download and installation process. (In Firefox on Mac OS, double-click the .dmg file.)

    If you still have trouble downloading Acrobat Reader, try using this direct download link. Select your operating system, language, and version, then click Download Now. Follow the onscreen instructions to complete the download.

    A system freeze or an error message indicates a specific problem with your computer or the installation process. To troubleshoot further, see the Solution associated with the error in the table below.
