Servers Supported

  • Windows Server® 2008 R2, 2012 R2, 2016 or 2019

For links and step-by-step instructions, see the ActivePDF Knowledge Base article Installing Products on Windows 2012 R2 Servers.

Database Requirements

  • Gibraltar® VistaDB

  • Microsoft® SQL Server 2012 R2 or later

    • SQL Server Enterprise is recommended for high-production usage.

Note: SQL Server does not need a local installation; for deployments with multiple servers using ActivePDF Reader Plus for the same web application, a local installation is not recommended. The SQL Server instance must be accessible via a standard SQL connection string from the application server where ActivePDF Reader Plus is installed.

Hardware Requirements

  • 350 MB of RAM

  • 175 MB of hard disk space (for application)

New Features and Enhancements

Reader Plus 4.4.0 supports the following new feature and enhancements:

  • Changes to the Orb menu bar: There is a new Hand pan button.
    Use the new hand panning tool to grab and move a PDF document around inside Reader Plus. Additionally, when you click the Marquee zoom in the View menu, and click to zoom in the document, the default pointer turns into the hand tool. Use this to move through the document instead of using the side scroll bar.

  • Add form elements multiple times with one click: You can add one or more shapes to your file by clicking the shapes once in the Tools menu, then clicking within your file. To enable the same functionality for the form field elements on the Forms menu, set enableRapidFireFormFieldAdd to true. You can then click once and add one or more text fields, check boxes, or radio buttons to your file without clicking the Form buttons each time.

  • Signatures and images on rotated pages: You can now add signatures and images to rotated pages.

  • Disable cleanup option: This option is useful when running multiple instances of Reader Plus on different servers that share the same database and cache server.
