Dr.Explain Perpetual Licenses are licensed on "per Windows user account" schema. The application is installed into a certain Windows user account. Therefore, you need a license for every Dr.Explain installation, even if all the installations were made on a single physical PC.
Basic maintenance is free for all users and includes email support. All minor updates (e.g., 6.1, 6.2, 6.5, ... 6.x) are free. There may be charges for major updates for those who ordered more than 12 months ago.
