Adobe has identified some issues with the current Reader download center. The engineering team is working to address them. Here are temporary workarounds for these known issues.
Issue: The Acrobat Reader installer can have trouble working behind some proxy server environments.
Workaround: Download the Acrobat Reader installer directly.
Issue: Antivirus software from vendors like Comodo, Jiangmin, and Rising incorrectly identifies the Acrobat Reader installer as malware. False reports from these vendors include “TrojWare.Win32.Trojan.Agent.Gen,” “Trojan/JmGeneric.bcy,” and “Suspicious.” Users also report “Failed to Initialize” errors and the installer getting quarantined.
Workaround: Antivirus software vendors and service providers are addressing this issue so that the Acrobat Reader installer is recognized as legitimate. Ensure that your antivirus signatures are up to date.
Make sure that your system meets the minimum system requirements.
Note: If you're running Windows 7 or 8, you can install Reader X or later. If you're running Windows 10, you can install Acrobat Reader XI or DC.

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).
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.
A high volume of activity can interfere with an Internet connection. For best results, try to download files when there is less activity (for example, late in the evening, early in the morning, or on weekends).
Try downloading the Acrobat Reader installer directly.
