From README.

Installation Instructions:

The trainer consists of two files, trainerv.asi and trainerv.ini
You need to copy both trainerv.asi and trainerv.ini to the game’s root directory.
In addition you will need the scripthookv.dll (the scripthook) and dinput8.dll (the asi loader) both can be obtained via:
http://www.dev-c.com/gtav/scripthookv/
For the list of options refer to the next two pages of this readme, to customize various options refer to the last page of this readme.
Thanks to Alexander Blade for both the Scripthook and the asi loader. I also “borrowed” a few things from his trainer, including the Vehicle Rockets and Car Speedup.
Thanks to Gforce who provided me with most of the teleports in the other teleports menu and thanks to Dalexy who provided all of the teleports on the main teleports menu.
Thanks to Kyle873 who provided the menu rect and did a lot of testing. Also Gforce and Dalexy provided testing.
