SPSS Statistics 23 is an older commercial Windows/macOS statistical package (released 2015). Typical install experience: straightforward installer, requires license (single-user or network), Java runtime bundled, GUI is stable but lacks newer features and modern UI improvements in later SPSS releases; performance fine for small–medium datasets, slower with very large data. Expect occasional compatibility issues on recent OS versions and limited support/documentation for this version. Use Oracle VirtualBox (free) or VMware Workstation Player
