Dear canard du futur, 

Thank you for your question and for sharing the details into Microsoft Q&A Forum. 

I completely understand how confusing it can be when a command prompt window appears and disappears quickly, it often looks like something went wrong. Please rest assured this behavior is normal for the Windows App Manager installer. The line Install License result: 0x0 indicates that the license installation completed successfully. The code 0x0 is a standard success code in Windows, meaning no errors occurred during that step. 

 It opens a command prompt during installation and closes automatically once the process completes. 

If you’d like to confirm the installation, please go to Settings > Apps & Features and check if Microsoft Windows App Runtime or Windows App Manager appears in the list of installed applications. 

For security and best practices: 

• Make sure you downloaded the installer from the official Microsoft website or trusted source. 
• Run the installer with Administrator privileges (right-click > Run as administrator) to ensure all components install correctly. 
• Keep your Windows and Microsoft Store apps updated to maintain security and compatibility. 
• Avoid running installers from unknown location. 

We hope these steps help you confirm the installation of Windows App Manager and ensure everything is set up securely. Wishing you a smooth experience using Windows App Manager and continuing your work without interruptions.
