We offer optional support contracts in combination with a new product license, or to renew an existing support contract. An active support contract includes the following advantages:

technical support with short response times

all minor (maintenance) and major (functional) updates included

early availability of bug fixes

maintenance releases and technical support available until the end of a product’s lifetime

additional licenses can be purchased until the end of the product's lifetime

Customers without an active support agreement can only use the licensed version, but not any later maintenance updates. This differs from earlier versions where we offered maintenance updates on a voluntary basis.

For a detailed description of support benefits refer to our General License and Support Conditions. The support fee is 20% of the license fee per year.

Support contracts can optionally be renewed automatically every 12 months until the support is expressly terminated by the customer. In order to terminate a support agreement with automatic renewal please inform us one month before the support expires.

Major Updates

A major update changes an older license to a license for a newer version on the same platform, thereby invalidating the old license. A valid license key must be supplied with each major update order. The following table indicates the fees for updates as a percentage of the target product’s list price:
