Download McIDAS-V Version 1.7u1

McIDAS-V runs on any platform that fully supports Java and Java 3D. Installers are available for Linux, macOS, and Windows, and McIDAS-V is tested and supported on all of these platforms. Other operating systems support the requirements in certain configurations, but have not been tested.

Jar files and source code are available for software developers, but should only be used by experienced Java programmers. The scripting and formula capabilities within McIDAS-V will be sufficient for most McIDAS-V users.

The current version of McIDAS-V is version 1.7u1 - in order to run McIDAS-V, there are certain minimum system requirements, as well as recommended configurations. If you are purchasing a new system for McIDAS-V, a 64 bit operating system with NVIDIA graphics card hardware and drivers is recommended. Performance will be better with faster processors and more memory. Please see the Complete System Requirements below for a list of all requirements and recommendations.
