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. Users of the BASIC 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.

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 BASIC version to the BUSINESS/ SCIENCE version with a license key (no re-install required). For more information, please visit our web site: ENVI_MET Try & Buy.

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.
