I am not with Laminar Research; just a flight simmer.
I presume you have purchased a 3rd party add-on aircraft from X-Plane.Org This business has no connection with the developer of the x-plane software namely X-Plane.Com Laminar Research does not sell 3rd party aircraft so you need to contact the seller namely X-Plane.org to solve your purchase problem.
In relation to the installation have a look at the following link from Michael Brown which can be found at https://www.youtube.com/watch?v=V4RjIxrhkXs Michael's company, XForcePC, is recommended by Laminar Research as the preferred company in the USA to build and supply purpose built PCs suitable for X-Plane.
The important message at the end is to load the 3rd party software into the Aircraft folder and not into the further sub directory named Laminar. Follow Michael's advice.
