We have 50 concurrent licenses for SPSS for Windows. These licenses are shared between version 6.1.4 and version 10.0.
Data files are interchangeable between the three versions.
Both programs are available to offices. Version 10.0 is in the public Windows Labs and also is available to distance education and degree link students through the galena server. Only Version 10.0 is Y2K compliant. The older version 6.1.4 will continue to be available from the server to offices that are still running Windows 3.1. However, since it is NOT Y2K compliant, be aware that data files containing date fields with two-digit years may not be processed accurately.
