Recently I attempted to install Windows Feature Dot Net Framework 3.5 on Windows 10 and saw the error below.
The resolution was to download a different larger CAB file then execute a different DISM command line.
Instead of installing the feature by name (“NetFx3”) we should install the CAB package filename (“”)
Hope that helps someone else. Cheers!
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:c:\sources\sxs # Error: 0x800f081f
DISM /Online /add-package /packagepath:c:\sources\sxs\microsoft-windows-netfx3-ondemand-package.Cab # microsoft-windows-netfx3-ondemand-package (68.9MB) # The operation completed successfully.
