Mplus Upgrade and Support Contract

An Mplus license comes with one year of upgrades and support as part of the purchase price. The Mplus Upgrade and Support Contract begins one week after the shipping date of the original purchase. After one year, an annual fee is required to keep the Mplus Upgrade and Support Contract up-to-date. Annual renewal reminders are sent out one month prior to the expiration date via email. If the Mplus Upgrade and Support Contract expires, in addition to the annual fee, the contract must be brought up-to-date for the month(s) it has lapsed. Besides the normal fee for these month(s), there is a 10% late fee. If a contract has lapsed for several years, it may be less expensive to purchase a new license.

The Mplus Upgrade and Support Contract includes access to the latest version of Mplus and product support through the term of the contract. The latest version of Mplus can be downloaded from the website under Support - Mplus Updates. It is recommended that a backup of the downloaded file be made because old versions are not available.
