IDL and ENVI are available for macOS, Windows, and Linux workstations. For labs, a single network license server (Windows and Linux only) can provide licensing for all clients. Faculty, staff and students may download installers for the software; CU Boulder username and IdentiKey password are required. (Note: An X-Windows manager is required for Macintosh; download and install XQuartz from their website.)

The current versions are IDL 8.8 + ENVI 5.6.


A new or upgrade license involves a $30 service fee.
