    Try this

    You need Windows Media for this (CD or USB).
    If you don't have it you can create is here: https://www.microsoft.com/en-us/software-download/windows10

    run an elevated command line and use the following: dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:D:\sources\sxs /LimitAccess
    (replace D: with your drive with the Windows Media)

    Cela m fait une nouvelle erreur :

    Les fichiers sources sont introuvables.
    Utilisez l’option « Source » pour indiquer l’emplacement des fichiers nécessaires pour restaurer la fonctionnalité. Pour plus d’informations sur la spécification d’un emplacement source, voir http://go.microsoft.com/fwlink/?LinkId=243077.

    Le fichier journal DISM se trouve à l’emplacement C:\windows\Logs\DISM\dism.log

    replace D: in the command line with the driveletter of your Windows Media ISO, CD or USb disk.

    So, if your Windows Media USB is F: you change the command to:
    dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:F:\sources\sxs /LimitAccess

    If it's still not working you must change a setting in group Policy:
    Open 'Edit group Policy'
    Browse to Computer Configuration, open Administrative Templates, and then select System,
    Open 'Specify settings for optional component installation and component repair' setting, and then select Enabled,
    Check both options and fill in Alternate Source Path: MediaDRIVEletter:\sources\sxs (change MediaDRIVEletter with your driveletter),
    Run gpupdate/force in the command prompt
    Run ism.exe /online /enable-feature /featurename:NetFX3 /All /Source:MediaDRIVEletter:\sources\sxs /LimitAccess again

    Disable the policy when you're done!
