# Send Buttons Disabled

The K3 Utility Send buttons are disabled if you are connected to a Elecraft KX3 rather than a K3. Use the Elecraft KX3 Utility to install firmware in your KX3.

The Send All New Firmware to K3 button is enabled only when there is new firmware available to send. All the required firmware files necessary to load the K3 must be present, and the available firmware revisions must be greater than the installed firmware revisionss for the firmware to be considered "new".

The Send All New Firmware to K3 and Send Checked Items to K3 buttons are disabled while copying files from Elecraft.

If the button is not enabled when newer revisions are shown in the Available column, try clicking Copy new files from Elecraft to copy the required files from the Elecraft server.

If the Send All New Firmware to K3 button is still disabled, required files may be missing from your Firmware folder. See Missing Files.
