@PeterJones said in Notepad++ v8.9.2 Release:
If you uncheck the Plugins Admin and Auto-Updater checkboxes, the gup.exe will not be installed, and Plugins Admin will not work. (I know there was a recent conversation and/or issue and/or PR about also having that remove the old gup.exe if it’s unchecked in the installer, but I cannot find it, and cannot remember whether the removal has been implemented yet or not.)
It is fixed and implemented in Notepad++ v8.9, see fix for no 3 in the list Commit e89b0be.
