I think this is the spot I could ask this.
Anyway, I have a few repaints of engines and the readme doesn't say if you can distribute them with your route. It also doesn't say who did it..all it says is:

To install extract to a temporary location and run packagesetup.exe.

With any repaints and files that don't say if you can give it out with your route..what should you do if you have it?
