Driver Only Files for installation

Sorry if this was already addressed,

Is there a place where I can download the drivers only for the Mega 2560? We have a device we are selling and want to include only the drivers and not the whole IDE environment or possibly include it in our software installation. We would like for the user to not have to install any drivers outside of our software. Any help would be appreciated.

Its free version you can tell customer IDE directly. Even you want to giver alone
just goto arduino IDE there is folder named Drivers. But these files not .exe files .when you connect the board you can choose the driver manually choose the driver for board.

I have attached the driver file for reference

drivers.zip (1.19 MB)
