Sales: Licenses

IES Software Licensing

IES, Inc. Owns the Software

Engineers use the software through an implicit license agreement. By purchasing the software you are agreeing to the license policy. Our service includes bug fixes and technical support in addition to business services.

You (or Your Company) Owns the License

Licenses may be activated or transferred as employees or hardware changes, as long as the license is active. You keep the license active by paying the annual maintenance or subscription fee.

Types of Licenses

  • Single-User Licenses
  • Network Concurrent-User Licenses
  • Annual Subscriptions (not available on all products)
  • Free Trials
  • Educational/Student Licenses

Single-user licenses are much simpler and more flexible for a small group of people (e.g. fewer than 5). Network licenses are more affordable if you have many users, where only a few need access to the products at any given time.

Single-User Licenses

The most popular license is a single-user license, which is assigned (by you) to a specific employee. You are in control of whose name is on the license. The license is for one person on up to 2 different machines (e.g. work & laptop).

The software is 'activated' on each machine you use via the Internet. You must deactivate to move the license to a new or different machine. See single-user license help for more details.

Network Licenses

For flexibility, we offer a floating license that allows multiple people access. You decide how many people need access at any one time and purchase that many license seats. You can add or remove seats in the future.

Licenses are accessed through a LAN, WAN or VPN system and users must be connected to a network share-folder that holds the license files. The system does not require running any special "server" software. See network license help for more details.

Optional Annual Maintenance

Paying annual maintenance of about 15% (varies by product) is the lowest-cost way to use licensed products. Technically, you do not need to pay maintenance fees. The fees cover new major versions, and licensing service and support. Previously installed and activated products will continue to work "indefinitely".

Expired Maintenance

  • You cannot activate expired licenses (e.g. new machine or hard-drive crash)
  • There is a $50 service charge to reinstate within 30 days of expiration.
  • After 30 days, you must upgrade your license to use it.


If your maintenance expires, you have up to 2 years to reinstate the license at a cost of 3x the annual maintenance. After upgrading you get the latest product version and one year's maintenance.

Annual Subscriptions

Subscriptions have a hard expiration date, and are limited to one machine activation, compared with 2 for the single-user license. This type of license is not currently available on all products.

If the subscription expires, the software stops working entirely. Traditional single-user or network licenses allow perpetual use of the latest product version even if you cancel maintenance. Either single-user or network-seat subscriptions are available.

Subscriptions are a good option if your needs are temporary or initial price is the most important factor for getting started.

Free Trial Licenses

If you download and run IES products without a license, they are automatically running as a free trial license that is time restricted. You register via the Internet. Free trials are fully functional during the trial period. The free trial of VisualAnalysis is the Advanced level.

Educational/Student Licenses

IES has an educational outreach program for VisualAnalysis.


Licenses are software and Internet based, so you get a license ID and a password to activate it. There are no hardware locks. Off-grid network licensing is possible for highly secured sites.
