A Recent Windows Update Is Causing App Installs To Fail, Here's The Workaround

If your system is throwing more UAC prompts asking for admin privileges and some application installs or repairs are failing, it may be due to a recent security update for Windows and Windows Server. Thankfully, Microsoft has posted a very easy temporary fix for the issue, at least for home users. If you're using a work PC and are not an admin on your PC though, you may need to ask IT for some help.

To avoid unauthorized changes in Windows, many applications request administrator privileges during installations, repairs, or when altering or creating files on the system. Due to a recent security update that mis-behaving, however, standard users on a system (i.e. non-administrators) may be prompted to input an administrator password for things like for things like running MSI repair commands, launching Autodesk applications, installing applications that configure themselves per user, enabling Secure Desktop, or deploying packages via Manager Configuration Manager (ConfigMgr) that rely on user-specific configurations.

If this bug crops, and a standard user runs an app that triggers an MSI repair operation without displaying UI, it will fail with an error message. The workaround is to simply run the application as an administrator, by right-clicking its shortcut (or installer), and choosing "Run as administrator" from the context menu. If the application is listed in your Start menu, right-click, select More, then "Run as administrator".

In situations where standard, non-admin users cannot “Run as administrator”, IT admins can workaround the issue by "installing and configuring a special Group Policy using Known Issue Rollback (KIR)".

Microsoft also said that it is “working to address this issue by allowing IT admins to permit specific apps to perform MSI repair operations without UAC prompts" for password input. This improvement will be released in a future Windows update. You can view a comprehensive official document on this matter via this link.
