Purchase policies (all products and services)

All sales are final. No returns. Prices, terms, and conditions are subject to change without notice. Textbook purchases: If you are a student ordering a textbook, ensure your instructor has ordered the book or contact us. Otherwise, if you are ordering a textbook, contact us for shipping and/or other charges. Software purchases: If you are tentative about a software purchase, request a demonstration copy. Software upgrades may apply some or all of their amortized cost to upgrade. Fees may be charged for software license transfers, extensions, and changes.

Software maintenance policy

Maintenance provides major version upgrades. Example: A 3-year license with 2-year maintenance provides upgrades for the first 2 years of the license. A back-on-track fee may be charged to renew maintenance for significantly expired licenses. Support varies with license, e.g., professional licenses are supported more than other licenses. Support for student versions is minimal. Significant help is available at the Get Started webpage. See the Professional/Research/Student Comparison Chart for more details. Reasonable support is provided. However, support is different than training or consulting.

Software license transfer policy

• A license transfer moves a license from one computer to another.
• The old license must be completely deleted and no longer used again.
• License transfer is provided for customers with current maintenance.
• License transfer fees are structured to discourage multiple licenses transfers within a few years.
  This may indicate a possible misuse, e.g., on multiple machines or by multiple users.
  Contact us for a discounted license transfer if you have extenuating circumstances.
