View and edit output .spo created in previous versions in SPSS

Because SPSS (version 16.0 or later) uses the .spv output format, it cannot open output files with the extension (.spo) from earlier versions of SPSS.

To view and edit .spo files in SPSS 16.0 or later, you need the Legacy Viewer utility. To get it, download the LegacyViewer.zip file, extract the contents, and then find and run setup.exe to begin the installation.
