We all know that in Windows, some apps require .NET Framework being installed, so that they could properly function. .NET Framework is an optional feature that you can enable using Turn Windows Features On or Off window. If you can’t enable .NET Framework feature from there, the alternative is this DISM method:

I am building VMs for both Windows 10 and Server 2016 (using MDS/MDT) and adding .Net 4.7.2 to base LTSB images (using PoSh remoting to automate it), and never ran into the 14003 error before. Thanks to your page, I have fixed this issue and added your solutions to my script.
^^ Glad we could help 😎
Hi Kapil, I’ve tried everything you’ve said and the ms repair tool too. Nothing works. I have Windows 10. Help! I would appreciate email. Many thanks!
^^ If you’re facing this issue while enabling .NET Framework, try enabling it from Turn Windows Features On or Off window instead. See if it works. Let me know if you’re facing this with some other DISM command.
