CCleaner 7.x Installer Behavior Change Notice

[rnz]

Starting with the 7.x release, the new CCleaner installer now triggers a Windows UAC prompt even when executed from an elevated context (such as Administrator or SYSTEM).
To accommodate this, the patch will still be made available as Non-Silent and marked with a special indicator to alert users:

This indicator helps ensure that users are aware of the expected UAC prompt before enabling the approval.

Additionally, the language parameter previously supported by SecTeer (based on Piriform’s official documentation) no longer functions as of version 7.x.
Our tests confirm that:

• The /L=<languageCode> argument is ignored by the 7.x installer
• The installer now defaults to English, regardless of the parameter specified

This means that localized installations are no longer possible. The patch will revert the application interface back to English until the vendor restores multi-language support.

Thank you for your understanding.
