The trainer is in the installer because it is faster and more convenient to use and there is no need to install other programs such as: ASI Loader (it is already included)
Updates in version 6.5:
Added the ability to install all cars in trainer.ini
Fixed problem with active or inactive phone when saving
Saving settings for police helicopters is now done in INI and saved
Attention! Preferably required patch 1.0.7.0 to install the trainer
