  • 1.  SPSS 28 uninstall issue

    Posted Wed December 28, 2022 04:25 AM
    When installing SPSS 29 on a PC with MS Windows 10 Pro (22H2) 64-bit, I kept SPSS 28 in another directory for security reasons (you never know what to expect with a new program version). Meanwhile, I have performed several analyses with SPSS 29 without any problems, and therefore I would like to uninstall version 28 now. In the Windows Control Panel, however, there is only one entry labeled "IBM SPSS Statistics" (i.e. without a version number), which has the installation date of version 29. An uninstall link for version 28 is no longer available.

    How can I uninstall version 28 without leaving any residue (also without "junk" in the registry)?

    Hi. As you saw when you installed v29 (in the opening panel of the installer), the new version overwrote v28, making uninstallation unnecessary. I presume that you copied v28 into another directory beforehand.

    There may be registry entries at HKEY_CURRENT_USER\Software\JavaSoft\Prefs\com\ibm\/S/P/S/S\/Statistics\28.0 that are no longer used and can be deleted; other entries there are being used.
