One software license is required per user-PC schema.

CASE 1: Dr.Explain is installed locally on workstations (desktop PC) and is launched locally.
You need as many licenses as many PCs the application is installed on.

CASE 2: Dr.Explain is installed on a public server and is launched remotely in different user sessions.
You need as many licenses as many user sessions could use the application simultaneously (concurrently).

License Options
There are two types of license:

• Annual 1 Year Subscription - One year (365 days) license with Premium maintenance and free updates included*.
• Perpetual license for current version only. For example, all 6.x updates are free. The 7.0 update will be free if it's released within next 12 months.

* Annual Subscription Licenses require you to purchase an annual license each year to continue to use the software. Perpetual licenses allow you to use the current version purchased with no time limit however you will need to upgrade if you require the latest version.

The perpetual license is available in Business or Home editions. The home edition is for individual licenses and has some restricted features when compared to the Business Edition. The Home edition displays a small watermark on images, collaboration between projects works in a demo mode and projects created with the Business edition are read-only for users of the Home License. The Business edition includes full functionality.

Are the new version upgrades paid?

• For perpetual licenses all minor updates (e.g., 6.0, 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. Upgrade pricing is usually offered at a discount from the new license price.
