The Program menu only has a single enabled menu item as well: Program .

All the user needs to do to perform a field upgrade is this set of steps:

1. Perform the action that will place the device into bootloader mode
2. Connect the device to the PC via a USB cable.  (USB Bootloader Pro is a HID device, so the PC will always recognize the device without having to load special device drivers.)
3. Run the PC program BLPro.exe
4. Click the Program | Program menu item, and watch the program upgrade and restart his target device firmware automatically.
5. Exit the BLPro.exe program.
6. (Optional) Disconnect the device from the USB cable.

That's it!  Field upgrades are safe, automatic, and painless.
