Putty Upgrade Does Not Remove Old Version

The Putty version .78 upgrade from .77 does not remove .77. This is not a problem with Automox, but is the expected behavior of the Putty .78 upgrade according to the release notes, which can be found here:

https://www.chiark.greenend.org.uk/~sgtatham/putty/changes.html

These features are new in 0.78 (released 2022-10-29):

• Note: installing the 0.78 or later Windows installer will not automatically uninstall 0.77 or earlier, due to a change we've made to work around a bug. We recommend uninstalling the old version first, if possible. If both end up installed, uninstalling both and then re-installing the new version will fix things up.

The solution is to manually uninstall version .77 or older.

The Automox worklet catalog includes a worklet called "Uninstall all apps under a specific version" that can be configured to remove the older version of Putty.
