Troubleshoot download problems

If one of the following errors occurs when you try to connect to or download from the Adobe website, work through the tasks below. 

  • Nothing happens.
  • A file stops downloading prematurely.
  • Any of the following errors occur:
    "The server returned extended information."
    "Connection failure has interrupted the download. Check your Internet settings and click Retry."
    "Cannot connect to server, server cannot be found."

1. Try to download Adobe Reader again.

Try to download Adobe Reader again by clicking the Download button.

2. Make sure that your Internet connection is stable.

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.

3. Download when there is less activity on the Internet.

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).
