Hi @佳鑫 包 ,

Is your computer connected to a domain or your personal PC? You'll need to install this feature under an account with administrator privileges.

If the error still happens, try installing .NET Framework from the ISO.

Download the ISO that corresponds to your version of Windows, mount it, and run the DISM command mentioning the source (e.g., H:\Sources\SxS) folder.

Example:

dism /online /enable-feature /featurename:NetFX3 /Source:h:\sources\sxs /LimitAccess

Best Regards.
