System Software Requirements

EASA's system requirements depend on the configured role each particular computer plays 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 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.

Additionally, an Excel Server requires more computational resources than the other server roles. See EASA Hardware Requirements.

EASA Server

Windows System:

  • Quad-core 3GHz
  • One of the following supported operating systems (64-bit recommended):
    • Windows XP Professional
    • Windows 7 / 8 / 10
    • Windows Server 2003 / 2008 / 2012 / 2016
  • 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. CentOS or Ubuntu).

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 at least 1024×768 ( greater is recommended)

EASA Client must have:

  • Windows XP, Windows 7 / 8 / 10
  • Network connection to EASA Server
  • Screen Resolution of at least 1024×768 (greater is 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 / 8 /10
  • Windows Server 2003 / 2008 / 2012 / 2016

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

Excel Server

It is common for an EASAP to utilize a 'live' Excel spreadsheet. This type of EASAP requires at least one dedicated Excel process per simultaneous User. In a large or computationally intensive spreadsheet this requires significant CPU and memory. In addition to the software requirements below, an Excel Server has very specific hardware requirements as well.

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

  • Excel 2003 / 2007 / 2010 / 2013 / 2016 (including Office 365 versions)

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

  • Windows XP Professional
  • Windows 7 / Windows 8 / Windows 10
  • Windows Server 2003 / 2008 / 2012 / 2016

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.

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

EASA supports only the English language version of Excel.
