Thank you for the reply.
I tried installing both win 10 sdk, and in the end win 11 sdk. I downloaded them from here

Then I installed the DirectX SDK which, as I understand it, includes Direct3D. I got that one here

Opened up UE5 after rebooting my computer and the Packaging options are still not showing up. Do I need to configure something manually perhaps?
