Note: There are two different license types depending on which release of DAQFactory you want to use the license on. The "Release 20.1+" version only works with the latest releases of DAQFactory, 20.1 and newer. If you are a new user or have upgraded, you should get this license. The "through 19.2" version will work on all releases of DAQFactory but should only be purchased if you are using an older release of DAQFactory: 19.2 or earlier. The Runtime license works for all releases of DAQFactory.
