“No Such Interface Supported” errors in Windows 11 often prevent users from opening files or launching applications, especially after system updates. This error typically points to broken application components, missing or corrupted DLL files, or issues with system files. As a result, users may find themselves unable to open images, videos, 3D models, or even basic text files with their default or preferred programs. Addressing this problem promptly restores normal file access and prevents workflow disruptions.

Repair or Reset the Affected Application

Repairing or resetting the problematic application is an effective way to resolve the error, particularly when the issue is isolated to a specific app like Photos, Paint 3D, or a media player.

Step 1: Open the Settings app by pressing Windows + I on your keyboard.

Step 2: Select Apps from the sidebar, then click Installed apps (or Apps & features depending on your Windows version).

Step 3: Scroll through the list to find the app that is generating the error. Click the three-dot menu (ellipsis) next to the app name and select Advanced options.

Step 4: Scroll down to the Reset section. Click Repair to attempt a fix without deleting app data. If the error persists, use the Reset button, which reinstalls the app and removes app data.

This process is especially useful for Microsoft Store apps like Photos or Paint 3D. For third-party apps, you may see a Modify button instead—use it to repair the program.

Reinstall the Problematic Application

If repairing the app does not resolve the issue, reinstalling it can address deeper corruption or missing components.

Step 1: Press Windows + R to open the Run dialog, type appwiz.cpl, and press Enter. This opens the Programs and Features control panel.

Step 2: Locate the problematic app, right-click it, and choose Uninstall. Follow the prompts to remove the application.

Step 3: Restart your computer to clear out any remaining files or settings.

Step 4: Download the latest version of the application from the Microsoft Store or the official website and install it. Launch the app to verify if the error is resolved.

Re-register DLL Files

Corrupted or unregistered DLL files, such as actxprxy.dll, can prevent Windows components and applications from accessing necessary interfaces. Re-registering these DLLs can restore normal functionality.

Step 1: Open the Start menu, type cmd, right-click Command Prompt, and select Run as administrator.

Step 2: In the Command Prompt window, enter the following command and press Enter:

regsvr32 c:\windows\system32\actxprxy.dll

Step 3: Wait for the confirmation message. If the error persists, you can attempt to re-register all DLL files in the System32 directory with the following command (note this may take several minutes):

FOR /R C:\ %G IN (*.dll) DO "%systemroot%\system32\regsvr32.exe" /s "%G"
Caution: Always create a system restore point before running bulk DLL registration commands, as incorrect registrations can cause additional problems.

Run System File Checker (SFC) and Check Disk (CHKDSK)

System file corruption can trigger interface errors across multiple applications. Running SFC and CHKDSK scans helps identify and repair corrupted system files and disk errors.

Step 1: Open Command Prompt as administrator (see previous instructions).

Step 2: Type the following command and press Enter to check and repair system files:

sfc /scannow

Step 3: Wait for the scan to finish. If any issues are found and repaired, restart your computer.

Step 4: To scan your disk for errors, enter the following command (replace C: with the appropriate drive letter if needed):

chkdsk C: /r /v

Step 5: If prompted, type Y to schedule the scan on the next restart, then reboot your computer.

Open Files from the Desktop or Directly in the Application

Some users report that moving the affected file to the desktop or opening it directly from within the target application bypasses the error. This workaround is useful when the error appears only when opening files from File Explorer but not from within the app itself.

Step 1: Move the problematic file (such as a .jpg, .png, .mp4, or 3D model) to your desktop.

Step 2: Double-click the file to open it, or launch the application first and use its File > Open menu to access the file.

This approach is a temporary solution for isolated cases and may not resolve underlying system issues.

Update or Restore File Associations

Incorrect or corrupted file associations can cause interface errors when opening files. Restoring default associations or updating them to the correct app can fix the issue.

Step 1: Open Settings with Windows + I, then go to Apps > Default apps.

Step 2: Scroll down and select Choose defaults by file type.

Step 3: Find the file extension (such as .jpg or .png) and set it to open with the desired application (like Photos or Paint 3D).

Alternatively, you can restore default file associations using a registry file provided by reputable sources or by resetting all default apps in the same menu.

Additional Tips and Workarounds

  • Update Windows to the latest version to receive bug fixes that may address the error.
  • Scan your system for malware, as infections can corrupt system files and application interfaces.
  • If the error started after a recent update, consider rolling back the update or using System Restore to revert to a previous state.
  • For persistent issues with a specific app, uninstalling and reinstalling the app from the Microsoft Store often resolves hidden corruption.

Resolving the “No Such Interface Supported” error in Windows 11 typically involves repairing or reinstalling affected apps, re-registering DLL files, and scanning for system file issues. Addressing these areas restores smooth file and application access, keeping your workflow uninterrupted.
