BUG: Cannot update, or repair, or even uninstall Acrobat

Whenever I check for updates and attempt the update, it ALWAYS fails with a message: No Valid sequence found for this set of patches. i think the error code is 1648.

Currently attempting to update to 24.002.20965.

    Since Microsoft blocked MSI repair by standard users since the Aug 2025 Windows 11 update, the Acrobat "Help>Repair Installation" feature no longer works.
    Adobe need to take this into account - shifting 'repair' to the CCDA, and have the installer include all features/components ADDLOCAL=ALL in the original installation.
