Hardware and Software Requirements

WEAP runs on all versions of Microsoft Windows from Windows XP to Windows 10, with a minimum of 256 MB of RAM and 100 MB of free hard disk space (4 GB of RAM is recommended, especially for larger models).

To install WEAP you must run the installer with Administrator privileges -- right click on the installer and choose "Run as Administrator."

Your computer screen should be set to a minimum resolution of 1024x768, but preferably even higher (e.g., 1920x1024), to maximize the presentation of data and results.

An Internet connection is not required, but is useful for tasks such as emailing data sets and receiving automatic updates to the software.

WEAP can interact with MODFLOW, MODPATH, QUAL2K and PEST, all of which are installed with WEAP.  WEAP can also communicate with Microsoft Excel, Word and PowerPoint if installed, but they are not required.  

Note: WEAP is designed as a single-user system. It is not intended as a multi-user system and we do not recommend running it from a shared network drive.

Although there is no Apple Macintosh or Linux version of WEAP, WEAP can be run on these systems inside a Windows "Virtual Machine," such as VMWare Fusion or Parallels.
