To fully activate your copy of WEAP, a valid License is required. Licensed users are given a user name and registration code that "unlocks" the read-only
of WEAP that can be downloaded from this site. The unlocked version is required when creating your own analyses. We are a non-profit research organization; these licensing fees help offset some of our costs of further development of WEAP and technical support.
Terms and Conditions
License fees are outlined below. Each license is for a 2 year period, and can be used simultaneously by an unlimited number of users at one site. During the 2 year license period, licensed users are entitled to free upgrades and to limited technical support.
SEI-US is a registered 501(c)(3) non-profit organization. All the money we collect in WEAP license fees (from users in high-income countries) goes to supporting developing country users or in further developing the software and documentation.
No copies of the software or the information required to unlock the software may be distributed to any other individual or organization.
One student, for use on their research while they are enrolled at a university or accredited educational institution in an industrialized country.(Students in developing countries can apply for a free license.)
NB: this license is intended for organizations using WEAP at a single site for their own purposes. This license does not entitle the organization to use WEAP at more than one site or for consulting purposes (e.g. to prepare analyses or studies for a client, or to conduct training or capacity building projects using WEAP).
After you pay the license fee, you will receive an email with instructions for the activation of your WEAP software to enable the "Save Data" feature.
Licensed users are entitled to free upgrades and limited technical support during the two year license term. If your computer is connected to the internet, WEAP will automatically notify you when upgrades are available. An on-line User Forum is available.
