IBM SPSS is a predictive analytics software, you can predict with confidence on what happens next to make smarter decisions, solve problems and improve outcomes.   Stony Brook University licenses this product through a SUNY contract as network license.  Part of that contract allows researchers to utilize the license in an off line (without network connectivity) mode called the commuter license.   This license is available for 7 days normally but by following the instructions below you the commuter license can be extended for 30 days.   This has been tested to work on Windows (PC) clients only.

Within the Windows (PC) on the SPSS client if you edit:
