  • Have you ever made any change/update to your system recently?
    There are many reasons why Error 0xc004d401 happen, including having malware, spyware, or programs not installing properly. According to the link shared by Umesh above, if your antivirus software or Digital Rights Management (DRM) software is incompatible with Windows, then you might have this issue. So please first have a check on this aspect.
    Please feel free to post back with any findings.
