I'm using a Microsoft brand 360 gamepad which has the vibrators and seems to work without issue in any game I've ever used. In this game however with joystick configured and enabled the options setting refuse to allow the turning on of force feedback giving a message on the bottom of the screen in flashing large green text that says there is no force feedback capable device.

Is this an incompatibility with this old software with current hardware or is there a way I can override this to get the force feedback working?
Rumble ≠ Force Feedback
A Gamepad doesn't have Force Feedback at all. Only some older Sidewinder Joysticks and most of modern Steering Wheels provide real Force Feedback.
