On how many computers may I install SPSS?
Each SPSS Single User license leased from SDS entitles you to install SPSS software on one (1) computer only. Purchasing one license and installing the software at work and at home (work-at-home use) are not permitted. If you wish to install the software in a lab or similar environment, either by using a central key server (in a lab environment, for example) you must purchase a concurrent user license.
Each computer that runs SPSS software must be licensed. If you have any questions about this information or to verify your current license count, please email firstname.lastname@example.org.
