Some Bentley products require a component called the Bentley IEG License Service to function. The component handles the licensing functions on behalf of programs that rely upon it. This article explains how the licensing works and how it differs from "trust licensing" which is used by other Bentley products.
The following products and versions require the Bentley IEG License Service:

SELECTserver provides the ability to check out or assign licenses for a specified duration. The licenses remain checked out to a user and computer and cannot be checked out elsewhere until the license is checked in again.
The Bentley IEG License Service utilizes this functionality. It automatically checks out licenses for a product as needed, usually when the product is first started. Licenses are checked out for a duration of two days. This duration ensures that a license is not prematurely returned if a product is running continuously overnight.
Once a license is checked out, the Bentley IEG License Service monitors the program that requested it. When the program closes, the license is automatically checked in again.
The Bentley IEG License Service follows the concept of "concurrent licenses." If a company has x number of licenses for a product, the Bentley IEG License Service will permit x users to utilize the product simultaneously. An additional user will be denied access until a license becomes available.
This concept differs from the concept of "trust licensing" which merely reports usage data instead of actively restricting users. For the sake of flexibility and fault tolerance, trust licensing products technically allow usage in excess of the total number of licenses purchased, but such use should be discussed with a Bentley sales representative for cost and conditions. Please refer to Understanding, Monitoring, and Managing Usage for more information about trust licensing and usage.
Note : More recent versions ( than what is mentioned in the table ) for most of these products do not use the Bentley IEG License any more and does not check out licenses. These products now use Trust Licensing.
If you are reinstalling an old application that requires the IEG License service, but no longer have that installer, first double check in your Bentley Downloads folder, look for iegls*.*. If it's not there file a service request and ask for IEGLicense Service verison 2.00.20.01 English 32 bit (iegls02002001en.msi).
