Common questions about updates

Why should I update?

Security and improved functionality. Updates safeguard your system against malicious attacks through PDF files.

If you've gotten multiple update messages, make sure the last update is fully installed. Some browsers download to a separate update window. In these browsers, double-click the Reader or Acrobat file to complete the installation.

How long is the installation time?
