I am using Microsoft Office 2021, 2024 on a few workstations. Starting with version v6.33.11465 (20 Feb 2025), Microsoft Office 2016 is no longer detected by CCleaner. I checked the version v6.32.11432 (22 Jan 2025) and it is working fine.
It is pretty strange because the registry key [HKEY_CURRENT_USER\Software\Piriform\CCleaner]
“(App)Office 2016” exists and it is set to “True”.
I consider this a bug in the application.
