ENVI has the following system requirements:

  • Operating systems:
    • Windows 10 and 11 (Intel/AMD 64-bit)
    • macOS 10.14, 10.15 (Intel 64-bit), 11, and 12 (M1 and Intel 64-bit)

    • Linux (Intel/AMD 64-bit, kernel 3.10.0 or higher, glibc 2.17 or higher)
  • Disk space: Approximately 4 GB for installation
  • Memory (RAM): Minimum of 8 GB
  • Number of processing cores: Minimum of 2, recommended 4 or more
  • Graphics card: Minimum of 1 GB RAM and support for OpenGL 2.0 or later


ENVI 5.6.2 has been tested with ArcGIS Pro version 2.9 and ArcMap version 10.8.

An X-Windows manager is required for macOS. ENVI was tested using XQuartz 2.8.1.

A Rosetta 2 emulator is required for Mac M1.

The 64-bit Windows installer contains 32-bit binaries so that you can launch ENVI in 32-bit mode on 64-bit Windows systems. This ensures interoperability with ArcGIS. To access the 32-bit version of ENVI, go to the Windows Start menu and select ENVI x.x > ENVI x.x (32-bit), where x.x is the software version.

Recommending the best hardware configuration for ENVI is difficult, as hardware needs vary depending on the type of processing that is anticipated. The following are items to consider when selecting a system configuration for use with ENVI.

Disk space

The amount of hard-drive space that is needed for ENVI depends on the specific workflows and data that will be used. Our technical support group uses systems with 1 TB of disk space, which is more than adequate for day-to-day use. However, this would not address the needs of a production facility that processes large amounts of data on a daily basis.

A solid-state drive (SSD) is highly recommended for optimal performance.

Memory (RAM)

Most image display and processing capabilities in ENVI and IDL have been designed to work with minimal amounts of system RAM. Having a lot of RAM can help to avoid occasional memory allocation problems, especially with large datasets. Tests have shown that 8 GB of RAM is adequate for most tasks run using the latest versions of ENVI and IDL. However, if you anticipate working with very large datasets, or if you are building custom applications with ENVI+IDL code, then you may consider adding more RAM to your system.

Graphics card

For optimal performance, your graphics card should have a minimum of 1 GB RAM and should support OpenGL 2.0 or later. Also be sure to install the latest drivers for your graphics card. If you anticipate implementing sophisticated graphical displays while building custom applications in ENVI+IDL—or if you expect to work with large datasets—then the more RAM the better.

Processors and Cores

ENVI only supports CPUs with the Advanced Vector Extensions (AVX) instruction set. In general, any CPU after 2011 will contain this instruction set.
