IES FAQ Answers
Single User
Single-user licenses or subscriptions are activated on a specific machine. Each license is allowed two activations for a single named person to use (e.g. at work and at home). This is a perpetual license, you may continue to use the installed product-version even after the expiration date. You keep the license active by paying an annual maintenance fee. IES products require Internet connections--at least periodically to verify the license.
Each product you purchase has a unique license ID and a unique activation password. For convenience, you may also use your login password to activate any product. When you purchase a license you are emailed a receipt with the license ID and activation password. You can also find your license ID in the Customer Portal at any time.
