EEMS utilizes a new licensing system. This system provides increased stability and ease of use for the users. Rental licenses are allowed and offline licenses may also be provided for users who don’t connect their machines to the internet. The following license models are now supported by EEMS:
1. Subscription License
A subscription license provides the full capability of EE and EFDC+ for a certain fixed period of time. Once this time has been exceeded the license will expire. During the subscription period the user may transfer the license to another machine by deactivating the license and then reactivating on the new machine. The EEMS License Manager form is shown in Figure 1.

2. Perpetual License
Perpetual licenses have no time limit in their use and provide the full capability of the EE modeling system without any kind of limitation. However, users will only be able to update their software to the latest version of EEMS within a certain time-frame agreed to in the sales arrangement. After that period of time, EEMS will still function normally but any bug fixes or new features which are added to EEMS after this date will not be accessible to the user. In order to access these updates the user will be required to have a valid maintenance contract with DSI. The EEMS License Manager will inform the user when this maintenance period is finished as shown in License Models#Figure 2. The user may then contact DSI to have their maintenance period extended if required.

3. Trial License
If you have been issued a trial license the license will expire after the trial period, usually 30 days. During this period, or .at the end of this period, you may need to activate a new license if DSI has provided it to you. To do this you need to remove the trial license from your machine. This can be done by opening the License Management tab shown the figures above, and selecting CTRL R.
