     - Windows may prompt you for permission to install the driver. Grant the permissions to proceed.

#### After Installation:

If you skipped the driver installation during the initial setup:

1. Rerun the LightBurn installer.
2. Select **Install EZCAD2 Driver** and complete the process.

#### Manual Installation:

1. Navigate to:  
   `C:\Program Files\LightBurn\EzCad2Driver\`
2. Run the file `dpinst-x64.exe` to install the driver manually.
3. Follow the on-screen prompts to complete the setup.

### Verifying Driver Installation

To confirm the driver installation:

1. Open **Device Manager** (press `Win + X` and select **Device Manager**).
2. Locate the device under **Universal Serial Bus devices**: 
     - Before installation: The laser appears as a **BJJCZ Device**.
     - After installation: The laser should appear as **USBLMCV2**, **USBLMCV4**, or a similar name.

#### Example Views:

- **Before Installation:** The device is listed as "BJJCZ Device."
