We use two different terms when talking about DAQFactory: "version" and "release". A "version" of DAQFactory determines what features of DAQFactory are available to you based on which license you purchased. Versions include "Lite", "Base", "Pro" and "Runtime".
If you decide that you would like to take advantage of the features of a different version of DAQFactory, you can purchase an upgrade license. The cost of this license is typically slightly more than the difference between the normal cost of license types. Once purchased, you will receive an unlock key. This key is 16 characters long, and usually starts with either Y or Z. To access the unlock windows, start DAQFactory and then select Tools-Enter Unlock Key and select the type of unlock you would like to perform. From here the unlock method is identical to the method used when you first unlocked DAQFactory.
