"We succeed when you succeed
Use for free, pay 5% when you ship" https://www.unrealengine.com/en-US/faq
"Get Unreal Engine 4 here, and with one free download access all engine features" etc...
I suggest you to load the free TwinMotion https://www.unrealengine.com/en-US/twinmotion
Like this the Epic Launcher will be installed too by default
Then you must be have no problem !
I have a friend who has that!
You can use the FBX format for import the assets ( 10 700 Hight Quality) inside Twinmotion !
Then use the Textures from Quixel inside TwinMotion
