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

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?

Hi,

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

If the "Mount" option doesn't appear in the right-click menu, mount using PowerShell.

I used the mount option with PowerShell and then tried to use a command by opening a command prompt and typing dism /online /enable-feature /featurename:NetFX3 /All but I still have the same problem
