It isn't pretty.

Win 10 refuses to allow the install to run.
I went through this before with the "stock" Orion and got it to work by installing the plane in my old desktop tower then transferring all of the folders and files to an SSD stick which I then transferred to the new machine.

I really don't want to bust out the old tower again and get it running. Does anyone have the EP-3 installed and could you hook me up?
Just zip the EP-3's main folder and files ( NOT the installer from the original download) and I'll take care of the rest.

PM me and I'll give you my e-mail addy.
