How do you install to a different location? (NOT Program Files (x86))

I want to use Quixel with UE4, to make the plugin work I have to link the plugins folder to Quixel Bridge.

Quixel Bridge cannot link to UE4 if it’s installed in Program Files (x86)

UE4 installs to x86 and, although the installation dialogue allows you to change the folder, it will still install Epic Games to x86 even if you choose a different folder.

What’s the point in the option to change folder if it still installs to x86?

How do you get Quixel to work with UE4 if Quixel cannot use the x86 file path?
