How to Fix: Why does the error "(app name) can't open while File Explorer is running with administrator privileges" occur?

The error '(app name) can't open while File Explorer is running with administrator privileges' occurs when attempting to launch a Modern UI app after restarting File Explorer with elevated privileges. This issue affects users who have recently set up their system using an administrator account.

This problem is frustrating because it prevents users fromaccessing certain applications, and the solution often requires additional steps that may be inconvenient. In this guide, we will explore the root causes of this error and provide two methods to resolve it.

🔍 Why This Happens

• The primary reason for this error is due to a limitation in Windows 10's security features. When File Explorer is running with elevated privileges, it creates a sandboxed environment that prevents other applications from accessing its internal workings. Modern UI apps, which rely on the Windows Runtime (WinRT), cannot function within this restricted environment.
• An alternative reason for this error could be related to the way the setup program interacts with the system. When a setup program is run with administrator privileges, it may alter the registry or create temporary files that interfere with the normal functioning of Modern UI apps.

🚀 How to Resolve This Issue

💡 Conclusion

In summary, the error '(app name) can't open while File Explorer is running with administrator privileges' occurs due to a combination of Windows 10's security features and potential interactions with setup programs. By restarting File Explorer without elevated privileges or launching Modern UI apps before restarting File Explorer, users can resolve this issue and regain access to their applications.
