How can I purchase a VASP license?

Send an email to licensing@vasp.at: Give some basic information about your affiliation in your email, so we can send you the appropriate license agreement forms.

Important notice: Some companies are selling illegal copies of VASP!
VASP can only be acquired legally in two ways:

  1. Purchase a license directly from the VASP Software GmbH (send an email to licensing@vasp.at).
  2. Purchase a license from Materials Design Inc. or their official resellers.

All legal licenses hold a signature of Georg Kresse or Doris Vogtenhuber, or are covered by a license agreement from Materials Design.
All legal copies are centrally registered.

How can payment of the license fee be made?

Payment can be done by wire transfer (preferred) or by cheque. Credit Cards are not accepted by the VASP Software GmbH. All bank details are given in the invoice to the vasp license fee which is sent together with the re-signed license agreement.

No.

VASP licenses are permanent licenses to the purchased software release and all minor upgrades to this release within the first three years after the license has been concluded. For any upgrades developed later, the license will have to be renewed.

To whom are VASP licenses given?

VASP licenses are given to well-defined research groups only. They are not department-or institution-wide, also they are not personal licenses. All members of a VASP-group have to work in the same organizational unit (Department, Institute) at the same location.

VASP-licenses are not transferable from one research institution to another one. Any transfer of a license to another group at the same research institution has to be approved by the VASP Software GmbH explicitly.
