How do I get my old output file to open in my new version of SPSS?
The SPSS output files (.spo or .spv with charts, tables, etc) are generally not backward compatible, so outputs created in a later version of SPSS can't be opened in earlier versions. Beginning with SPSS 16, output files are written in the .spv format. Therefore, it is not possible to read older .spo files directly into SPSS 16. The SPSS 16 for Windows CD-Rom includes a Legacy Viewer (SPSS 15.0 Smartviewer) which should be installed on machines where .spo files may need to be read. These files should be opened in the Legacy Viewer available for download here.
