System Requirements

Version 3.7

ArcGIS API for Flex system requirements

The following prerequisites will help you get started with the ArcGIS API for Flex:

Access to services

Optionally, access to ArcGIS Server 9.3 or later. If you do not have your own ArcGIS Server, you can work with services accessible from ArcGIS Online and elsewhere. Not all services used in the ArcGIS API for Flex need to be ArcGIS Server services. Please see Types of layers for additional information regarding what can be used within the API.

Apache/Adobe Flex SDK versions

Adobe Flex SDK 4.6 (or later). If not using the Adobe SDK, you can also use the Apache Flex SDK 4.8 parity release (or later). The Adobe Flex 4.6 SDK accompanies Adobe Flash Builder 4.6 and 4.7, but you can also download it separately if you are using an older version of Flash Builder, or if you are using a different IDE. For detailed Flex framework system requirements, read the Flex SDK system requirements.

Adobe Flash Player versions

Applications compiled with Adobe Flex SDK 4.6 or Apache Flex SDK 4.8 require the use of at least Adobe Flash Player 11.1. For more details, read the current Flash Player system requirements by Adobe.

Adobe AIR versions

When creating mobile applications using Adobe AIR, the minimum supported version is 3.1. For more details, read the current Adobe AIR system requirements by Adobe.


This is not to be confused with the 3.5 minimum version needed to run the ArcGIS Viewer for Flex Application Builder.

Development environments

The most popular Flex development environment is Adobe Flash Builder. It is not free; however, a 60-day evaluation version is available. The ArcGIS API for Flex is compatible with all versions of Flash Builder 4.6 and later. For detailed Adobe Flash Builder system requirements, read the current Flash Builder system requirements by Adobe.

Although Flash Builder is the environment used in the Getting started tutorial, it is not a requirement. You could write your own Flex code in a text editor, e.g. Notepad, and compile using the command-line with the free compiler. In addition to this, you could choose an alternative such as the open-source FlashDevelop and/or Microsoft Visual Studio plug-ins.

ArcGIS Server versions

Certain functionality requires a specific minimum version, for example, advanced printing requires ArcGIS Server 10.1 and editing requires ArcGIS Server 10.0. See the table below for additional information.
