Download ENVI-met V4

Below you will find the recent ENVI-met V4 release. From now on, there will be a Winter Release (around end of October to Mid November) and a Summer Release (around end of April) each year. The Winter Release usually brings new features to the system while the Summer Release is mainly dedicated to small updates and bugfixes. Users of the LITE (Basic before) Version must update to the newest versions within one month. In addition, there will be “Hot Updates” available if required to those who can't wait for the next official release.

ENVI-met LITE is limited to domains of 50 x 50 grids.

License Conditions

The license conditions depend on the version of ENVI-met you use. You need to agree to the exact and actual license conditions when installing ENVI-met. A general overview can be seen here: License Conditions

System Requirements

WINDOWS 7, 8/8.1 or 10 64Bit, ENVI-met can be installed on 32 Bit Systems but large models (above 200×200) probably will not work due to memory shortage, 3 GB Memory and 1 CPU core for each active simulation, a lot of disk space (expect 5 GB for one 24-hrs Simulation). ENVI-met might run in a virtualized environment, but calculate slower and will need non-standard settings.

Upgrading to full BUSINESS/ SCIENCE Version

The installation package found here can be upgraded from the trial LITE version to the BUSINESS/ SCIENCE version with a license key (no re-install required). For more information, please visit our web site: ENVI_MET Buy Now.

Already a user of the full version? Your key remains valid for all updates during the license time. If you install ENVI-met into the same folder like the previous version, your license will be updated automatically. If you install the new release into a different folder, please use your private and active as described in the accompanied PDF. Also see the notes in the download section below…

Parallel Computing/ Backward compatibility

ENVI-met now offers parallel computing in the BUSINESS and SCIENCE versions. Before you start using the new version, please read this section: Parallel Computing in ENVI-met

Installation remarks

With the Summer 19 release, a new license key system is introduced. Licensed users can still download and continue to use the Winter1819 version and migrate to V4.4.3 at a later time. You can also install the new version parallel to old one if you use different folder.

Users without a license must download the recent Summer 19 release.

Important: You must have or get full read/write access to the install folder during install, otherwise the software won't work.

Summer 19 Release

To use an existing license, this release requires a one-time automatic license key update for licensed users which needs administrative interaction. In a running project or class, it is recommended to allocate a free time slot for this process. Further information about the license conversion can be found here. If you are having trouble with the activation please contact license@envi-met.com
