No, you do not need to download again or re-install the software. You will need to apply an authorization code to license the software. If you do not have that authorization code, visit the SPSS License Key Center (link resides outside IBM).
Fixed Term and Perpetual licenses are the traditional way to purchase SPSS Statistics through an IBM seller or IBM Business Partner. Software authorization codes are required and software updates are manually downloaded from Passport Advantage or Fix Central.
The SPSS Statistics paid Subscription plan can be used offline, but it requires a user to authenticate their license at least once every two weeks. After 14 days of offline access, the application will stop functioning until an internet connection is established and you log in with your IBMid. A working internet connection is required for this step. We recommend that you download the free trial subscription to ensure compatibility prior to making purchase.
If you have downloaded a trial version of IBM SPSS Statistics and have now received your SPSS authorization code from ITS, follow the instructions below to license your software on the Macintosh operating system. You can also use this procedure for the annual subscription renewal for your product. 153554b96e
