CAS BACnet Explorer can be licensed using a USB hardware key in addition to software-based activation. When a USB product key is used, license updates are applied using a dedicated utility called KeyUpdater.exe. This page explains what the USB Key Updater is, when it is required, and how it is used with CAS BACnet Explorer.
The USB Key Updater is a standalone application provided with the USB license package. It is used to program or update the license information stored on the physical USB key and does not modify the BACnet Explorer software installation itself.
What Is the USB Key Updater?
The KeyUpdater.exe application is used to update USB-based product keys for CAS BACnet Explorer. These USB keys store license information directly on the hardware device and must be updated when a license is issued, renewed, or modified.
Unlike software activation, which relies on entering a product key within the application, USB activation requires the license data to be written to the USB device itself. The Key Updater utility performs this operation by communicating directly with the USB key when it is connected to the PC.
