Driver Canaima Letras Rojas Windows 7 64 Bits Link
I need to explain that drivers are OS-specific. Canaima provides drivers for Linux; if the device is being used with Windows, they need the Windows drivers from the manufacturer. Also, Windows 7 64-bit is not supported anymore since January 2020, so security risks are a concern. They might not be able to find drivers for Windows 7 anymore due to its end-of-life status.
