ADE 1.70 won't load in P3D

When I try to load ADE (as a administrator) 1.70 choosing P3D v.3.4.18 as the sim, I receive this error message:

Doesn't mean anything to me!
When I load ADE with FSX, it works fine.
My PC runs on Win 10 64 bits.
My user account has administrator rights.
What could I do?
