The latest versions of Understand takes about 600-700MB of installation space, depending on which OS it is installed on and will run on Windows x64 (Windows 10 and later), Linux 64bit (CentOS and RHEL 8.4, Ubuntu 20.04, and later) and Mac OS (Mohave 10.14 and later). For larger code bases the more RAM the better. We recommend 1GB / Million lines of code, it will run on less, but it is much slower.
Build 1096 and older will run on Windows x64 ( Windows 7 and later), Linux 64 bit ( CentOS & RHEL 7.6, Ubuntu 18.04, and later ) and Mac OS ( High Sierra and later ).
Build 1077 and older will run on Windows x64 and x86 ( Windows 7 and later ), Linux 64 bit ( CentOS & RHEL 7.4, Ubuntu 16.04, and later ) and Mac OS ( Sierra and later ).
Use the older builds of Understand if you need a version to run on an older machine.
