    Hi,

    I think it's drive C, but I can't see any option to mount it when I right click on it

    The article doesn't anywhere mention C:\Sources\SxS. It points to the Sources\SxS folder on the mounted ISO.

    Did you mount the ISO? Which drive letter is it?

    I used this command dism /online /Add-Package /PackagePath:C:\Sources\SxS\microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.cab and then followed by dism /online /enable-feature /featurename:NetFX3 /All /Source:C:\sources\sxs /LimitAccess as suggested by this article: https://www.winhelponline.com/blog/error-0x80070490-net-framework-3-5/. 

    Thank you

    May I know what is C:\Sources\SxS? Does the folder exist?

    Did you copy the CAB file to that folder?

    Also, what's the exact command line did you use?
