eLicense & USB Comparison

AFT software utilizes one of two forms of copy protection 

    1. eLicense: internet based and requires only a license text file
    2. USB Key: physically contains the licenses and requires additional software to run


The eLicense requires an internet connection to access the cloud based licensing service. This service keeps track of which computers have the software active. Any changes in licenses such as a new product or version upgrade can be changed nearly immediately. This option requires minimal additional configuration and we recommend it for most users.


A USB Key can also be used. This option does not require internet access but requires additional drivers and copy protection. If a network version is desired, further configuration is required on all machines, and a license service must be kept running on the server with the USB Key plugged in. The USB Key physically contains licenses for AFT products - which means that the key (and associated licenses) can be lost. License changes can be made to a USB Key remotely, but requires the exchange of files via email and the use of a utility program.
