Non-admins might receive unexpected UAC prompts when doing MSI repair operations

(Updated 11/26/25: Additional improvements were added to the Resolution section.)
A security improvement was included in the August 2025 Windows security update (KB5063950) and later updates to enforce the requirement that User Account Control (UAC) prompt for administrator credentials when performing Windows Installer (MSI) repair and related operations. This improvement addressed security vulnerability CVE-2025-50173.
As a result, after installing the August 2025 Windows security update and later updates, UAC prompts for administrator rights can appear for standard users in the following scenarios:
- Running MSI repair commands (such as msiexec /fu).
- Launching Autodesk applications, including some versions of AutoCAD, Civil 3D and Inventor CAM, or when installing an MSI file after a user signs into the app for the first time.
- Installing applications that configure themselves per user.
- Running Windows Installer during Active Setup.
- Deploying packages via Manager Configuration Manager (ConfigMgr) that rely on user-specific "advertising" configurations.
- Enabling Secure Desktop.
If a standard user runs an app that initiates an MSI repair operation without displaying UI, it will fail with an error message. For example, installing and running Office Professional Plus 2010 as a standard user will fail with Error 1730 during the configuration process.
Resolution:
After installing the September 2025 Windows security update (KB5065767) or later updates, UAC prompts will only be required during MSI repair operations if the target MSI file contains an elevated custom action. This requirement is further refined after installing Windows updates released on and after November 11, 2025, so that UAC prompts will only be required if the elevated custom actions are executed during the repair flow.
Installing the latest Windows updates will resolve this issue for apps that do not execute such elevated custom actions, such as Autodesk AutoCAD.
Since UAC prompts will still be required for apps that perform custom actions, after installing the September 2025 update, IT admins will have access to a workaround to disable UAC prompts for specific apps by adding MSI files to an allowlist. For details, see the KB article: Unexpected UAC prompts when running MSI repair operations after installing the August 2025 Windows security update.
