See the license comparison table for a summary of the differences between the different types of EES licenses.

A single-user license is intended for use by one person only. The name and affiliation of this person are displayed in the start-up screen. The program may be installed on multiple computers provided that only the designed person uses the program.

An N-user (for N<=20) license allows EES to be used by N specific individuals designated by the license administrator. The N users must all be members of the same work unit and be located at one physical location. An N-user license is not a floating license. Only the designated users may use the program. The licensee must provide appropriate monitoring to ensure that only the N specified individuals have access to the software.

An N-user (for N>20) license allows EES to be used by N specific individuals designated by the license administrator. The N users must be members of one company, but the users do not all have to be located at one facility. An annual fee of 20% of the current cost of the N-user license must be paid within 30 days of the anniversary of the original purchase. This fee provides access to the F-Chart website for the current version of the software and technical support.

64-bit Version

The standard EES program is a 32-bit application that is designed to run on both 32-bit and 64-bit Windows operating systems. Professional versions of EES can be optionally upgraded to a true 64-bit application. Purchase of a 64-bit license is required. See the 64-bit license information for details.


Academic licenses for EES are available for education institutions that are using EES for formal educational activities. Thesis research that leads to a advanced degree is considered an academic activity and it is allowed under the license agreement. Consulting or use by sponsors outside of the academic institution is not allowed with an academic license. An Academic license requires an internet connection with an IP address that maps to the university.

A single-user Annual license is also available.
