For the Windows version of HealthScreen, you can download the program as a demonstration version. The demo version will operate for 10 days. When the allotted time has expired, you will be unable to use the program and will have to purchase it from Human Kinetics. After installation, you’ll see a screen asking you to choose either to register the program or run it as a demonstration version. Follow the on-screen instructions. Make sure to note the phone numbers to call (both for U.S. and international orders) in case you would like to purchase a copy of HealthScreen once your demonstration version has expired.
