Your Serial Number is created from the Hardware Address of your computer. FlowJo Version 8, 6, 4 and 3 use different serial numbers.

Installing Serial Numbers:

• Download the current version of FlowJo or copy FlowJo from the CD to your computer.
  
• Launch FlowJo by double clicking the application icon.
  
• Click the Register License button in the Serial Number dialog box (this will take you to www.flowjo.com/register.html)
  
• Complete the online form to request your serial number.
  
• When it arrives by e-mail, launch FlowJo and enter the serial number in the dialog box.
  
• Serial numbers are issued for one year, and are renewed automatically to give you the flexibility to assign your user license to a different Macintosh.
  

NOTE: If you are using OS9 for version 6 and before, and there is missing text in dialog boxes, or FlowJo asks you to update your CarbonLib you need to replace the CarbonLib in your computer's Extensions folder. Download a new CarbonLib or find the CarbonLib in the OS9 Users folder on the FlowJo CD. Copy the file to the Extensions Folder on your computer to replace the existing CarbonLib. Restart your computer.

Trouble Shooting:

-Serial Numbers and dongles are two different methods of license protection. If you have a serial number, you do not need a dongle.
-Version 3 and Version 4 use different serial numbers.
-FlowJo checks to make sure the computer's date and time (and all the files on the computer) are correct before it will run. You can use Disk First Aid or Disk Doctor to find and correct the files that are improperly dated.
-Capitals are important. It is best to copy and paste the serial number into the dialog box.
-Check the hardware address - if you are using an airport hub, this gives a different hardware address to FlowJo. We recommend turning off the Airport connection.
-The hardware address of the computer will show up at the bottom of the Serial Number dialog box. If the Serial Number dialog box does not come up automatically when FlowJo is launched, open it from under the FlowJo menu (in OSX) or the Apple menu (in OS9).
-Alternative methods for determining the hardware address:
OS9 - open the TCP/IP control panel and choose Get Info from the File menu.
OSX - open the Network dialog (from the System Preferences) and click on TCP/IP.
