Installation requirements

Size of install set: less than four megabytes for Marxan, less than three megabytes for Marxan with Zones.

Operating System: Any Microsoft operating system will suffice, even a really old one. As a rule of thumb, if a computer is powerful enough to process the GIS layers (using Arc9 or other GIS) used to build a Marxan dataset, then it will be more than adequate for running Marxan.

You may require a more powerful computer if you want to speed up the generation of many solutions with Marxan. It can take many hours or several days to produce a large number of solutions for a large Marxan dataset.
