thank you i used dism /online /add-package /packagepath:E:\sources\sxs\microsoft-windows-netfx3-ondemand-package.cab and that worked for me too.
thanks again for your helpful
@ottomon1 welcome to Ten Forums,
I'm glad to hear you were able to find a solution that worked for you
Note: My windows 10 installation media (1511) didn't have the required 'sources' folder on it. I had to use the media creation tool to build a dvd which had the required folder.
Then the following command worked for me!
dism /online /add-package /packagepath:E:\sources\sxs\microsoft-windows-netfx3-ondemand-package.cab
I tried all of the above to no avail. What did work for me was to go to the Windows component option in Control Panel >Programs and Features and check the .Net Framework 3.5 checkbox and the 2 listed under it as well. If I just checked one it didn't work and I got the error code we are all getting. Not sure if this will work for everyone but I have been racking my brain on this and this is the only thing that worked for me.
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:F:\x64\sources\sxs
