Error while downloading .NET Framework 3.5

Question

Answer 1

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.

The error is an access denied error. You should ensure that the user attempting to download and install has necessary permissions to the file system and the rights to install software. Alternatively download the file from another computer and then copy it over.
