How to Change Your NCSS, PASS and/or GESS Serial Numbers

Occasionally, you may need to change your serial number. This may be because you are upgrading to a newer edition of NCSS, PASS, and/or GESS or because you are changing from the trial version to the fully-licensed version. To change your serial number, do the following:
  1. Start NCSS, PASS, and/or GESS and go to the NCSS/GESS spreadsheet or PASS Home Window.
  2. From the Help menu, choose Serial Numbers.
  3. Write down the old serial number in case you need it. Replace the old serial number with the new serial number.
  4. Click OK to close the Serial Numbers window.
  5. Quit NCSS or PASS.
  6. Start NCSS or PASS up again. The program is now using your new serial number. If you have entered an incorrect serial number, you will get a 7-day trial or expiration notice.

"Your [PASS] routines are flexible and easy to use and your customer service and support is A-double-plus."

As Statistician teaching statistics in the University, I have to say that NCSS is the tool that I have used since 1997. With all the procedures that you need for research or to make a good, informative presentation, it can be used for teaching in a university. Here in Idesem-Chile we have found it to be the best tool to support our measurement activities. I recommend this tool to make your job more enjoyable!
