As of March 1, 2019 all projects using TransModeler should be analyzed using TransModeler 5 Build 7245. The only exception is for projects that included calibration with a previous Build. To request Build 7245 each firm will need to contact Caliper and request it. Do not request "the latest build" – please request Build 7245 specifically. You can contact Caliper at firstname.lastname@example.org; however, you must provide them with the Serial Number from the >Help>About screen in TransModeler/TransModeler SE. Also, you can go to >Help>E-mail Technical Support and it will include the Serial Number automatically.
