System Requirements

EASA's system requirements depend on the role each specific computer has within the EASA system.

The three computing roles are:

There are no special requirements for a Database Server.

EASA is a high-level programming language thus EASA applications can vary in their computational resource requirements. The system requirements listed below are recommendations based on typical use cases. Performance and practical system requirements will depend on the specific application, system configuration and usage scenario of the EASA system.

EASA Server

Windows System:

  • Quad-core 3GHz—greater CPU resources will support a higher number of concurrent Excel processes
  • One of the following supported operating systems (64-bit recommended):
    • Windows XP Professional
    • Windows 7
    • Windows 8
    • Windows Server 2003
    • Windows Server 2008
    • Windows Server 2012
  • 20 GB minimum of available hard-disk space for installation and file storage
  • 8 GB of available RAM

The above requirements can be adjusted downward for low-user or low-complexity EASA deployments.

Linux System:

In addition to the above, an up-to-date RHEL or Debian distribution or a derivative is recommended
(eg. Ubuntu, CentOS).

If you plan to use Linux for your EASA Server, we recommend using a well- supported, current distribution.

Client Computer

Web Browser Client must have:

  • Internet Explorer 8 or over, or current Mozilla Firefox, Chrome or Safari
  • Network connection to EASA Server
  • Screen Resolution of 1024×768 or greater (recommended)

EASA Client must have:

  • Windows XP, Windows 7 or Windows 8
  • Network connection to EASA Server
  • Screen Resolution of 1024×768 or greater (recommended)
  • 150 MB of available hard-disk space for EASA Client installation

Compute Server

EASA supports communication with Compute Servers running the operating systems below:

  • Windows XP Professional
  • Windows 7
  • Windows 8
  • Windows Server 2003
  • Windows Server 2008
  • Windows Server 2012

For additional details on configuring Compute Servers see Configuring Compute Servers.

Excel Server

An Excel Server requires one of the following 32-bit versions of Microsoft Excel:

  • Excel 2003
  • Excel 2007
  • Excel 2010
  • Excel 2013.

The Excel version above needs to be running on one of the following operating systems:

  • Windows XP Professional
  • Windows 7
  • Windows 8
  • Windows Server 2003
  • Windows Server 2008
  • Windows Server 2012

Office 365 is not supported in this version of EASA.

EASA requires the Office feature called Visual Basic for Applications, found under 'Office Shared Features' in the feature tree when customizing the installation of Office.

EXPORT TO PDF requires 'Excel 2007 Service Pack 3' or later Excel version.

'Excel 2007' versions prior to 'Service Pack 3' can be upgraded with the official plugin from Microsoft to use with EXPORT TO PDF.

The plugin can be downloaded from Microsoft's website here.

In all cases, the 32-bit installer of Excel must be used even when installing on a 64-bit operating system.
