By purchasing an IES Software License, you are using the software through an implicit License Agreement.

All IES programs can be licensed for commercial use through one of three different License Types. Each Software License can be purchased under two different License Terms.

License Types

Single-User

A single license assigned to one individual and can be installed on two computers (e.g., work and home), for use by the named individual only.

Local Network

A single license with access for multiple users. Concurrent access is limited by the number of network seats purchased.

Cloud Network

Similar to a local network except the license is hosted in the cloud, eliminating the need for you to have a server.

License Terms

Subscription

Licenses are renewed annually at the current subscription price. Active subscriptions have access to the latest product version and support.

Perpetual w/ Annual Maintenance

Licenses that offer long-term ownership with lower-cost annual maintenance for updates and support. The initial purchase includes the first year of maintenance.

The Annual Maintenance fee for a Perpetual license keeps the license current with updates and support.

Perpetual licenses cannot be activated or transferred without an active maintenance plan.

Subscription vs. Perpetual Licenses

Below is a comparison table highlighting the difference between the License Terms.

Maintenance Coverage - Explained

Each new Perpetual license (Single-User, Network, and Cloud) is covered by one year of software maintenance, which covers all major-version upgrades, technical support, and licensing services. Current maintenance rates can be found in our online Cart Builder. Maintenance costs will change over time as pricing is updated. Any active Maintenance plan will be renewed at the then current rates.

Software licenses with Expired Maintenance will not be allowed to activate or change machines. If a computer crashes, breaks down, or has hardware changes, you will be unable to access your software until your maintenance is renewed or upgraded. If a license has been expired for greater than one year, you may be required to purchase a new license (i.e. your license will not be eligible to reinstate the maintenance plan). Please Contact Sales if you have questions.

Licensing Services & Technology

Licensing services includes bug fixes and technical support in addition to business services.

Single-User and Local Network license files are stored locally on your hard drive or network share. Cloud license files are stored remotely on a licensing server. In all instances, an internet connection is needed to verify the license is Valid. There are no hardware locks or USB dongles required.

Licenses may be activated or transferred as employees or hardware changes, as long as the license has not expired. You keep the license active by renewing the annual maintenance or subscription fee.

Off-grid Network licensing is possible for highly secured sites that cannot provide access outside of their network environment. Please Contact Sales if you require additional information.
