SPSS 16
I haven't included uninstalls for previous versions as I expect you would change your default 'PROFILE' to <package package-id="spss16" /> which would force SPSS15 to uninstall. There are three additional SPSS16 patch files included (there may be more now). Obviously, substitute COMPANYNAME, ISX_SERIALNUM and LSHOST with your own organisation.
I have included AMOS16 and the Legacy Viewer to open files for SPSS15 and earlier.
You can download all the patch files and the Legacy Viewer from the SPSS website.
