So that the Community can help you better, we will need to know exactly which camera model you're using, and which software you're looking to update. That, and any other details you'd like to give will help the Community better understand your issue!
Thanks and have a great day!
There have not been new firmware updates for the camera, but there may be newer software updates for the Canon software on your computer.
You can find the latest software here and compare to the versions you have installed: http://www.usa.canon.com/cusa/consumer/products/cameras/slr_cameras/eos_rebel_t3_18_55mm_is_ii_lens_...
