I downloaded a model from the 3d studio

So I downloaded a model from the 3d studio and I can’t get it to open in unity. Any ideas? The thing I downloaded is on this link http://www.the3dstudio.com/product_details.aspx?id_product=72335

They would convert the .max model for free if you purchase the model but being free they may not convert it to .fbx

how do i convert it into .fbx?

You can only use a .max or .mb if you have the associated program installed on your system.

In this case, you’d need 3D Studio Max.

you cant use it in your game it says for personal use only
