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

An unstable Internet connection can prevent you from downloading from other websites. Try downloading a file from another website, such as www.microsoft.com, www.apple.com, or www.mozilla.com. If the problem persists, contact your network administrator, help desk resource, or Internet service provider (ISP). See Resolve an unstable Internet connection to the Adobe website or FTP site for details.

After you establish a stable Internet connection, try to download the file again. If the original attempt to download the file was interrupted, restart the download process within the web browser you were using.
