Retrologue doesn't validate in Logic Pro X


I Installed the trial version of Retrologue in my high Sierra MacBook Pro, and when I start Logic it doesn’t validate, it says sometime of: Initialize: result -1, and something about not finding the plugin.vst3 file

I have a Audient id14 on the way with a Retrologue license free because of the Arc program, so when it arrives I’ll have the same issue?

Help please

Many thanks

MacBook Pro 2012
