Instructions for Installation of SPSS
Starting with version 13 of SPSS, the license model has changed. Each SPSS installation for single user licenses must be performed with a unique authorization code. The authorization codes/keys for the installation of the SPSS software can be found on your SPSS order confirmation, which you received after ordering your SPSS license via the RWTH Aachen University software store.
If you have ordered a network license, the license server has to be set. (see ITC-README_Lizenzinfomrationen.txt on the download server).
