One-year access to the latest software versions and online services. Your purchase of AVDI includes updates to the basic software, tools, and online features for one year. In order to keep the software up to date and to be able to use the online features after this time, we recommend that you purchase an AMS (Annual Maintance Subscription). It requires purchase every year. *Note: AMS does not provide any additional generation, this is provided by the SPS (Support Plan Service) function. An active AMS function is required to purchase additional special features. Please enter your software configuration number to check the price.
