We understand that the end-users’ institutions may have additional regulatory and compliance requirements that necessitate changes to the end-user license agreement. Additional fees will be assessed if changes are proposed to cover the cost of negotiations.

Classroom licenses with technical support are available at a substantially reduced rate. Please contact us for more information.
