ARC125 driver installation:

To install the Uniden UBC125/BC125 drivers under Windows XP/Vista/7/8/10 please follow this procedure:

After installing the driver the scanner should be listed as either a BC125 or UBC125 in the Windows device manager. This indicates the driver was properly installed. After installing the driver the ARC125 software should recognize the scanner.

Windows 8/10: Some version of windows 8/10 by default will not allow installation of 'unsigned' drivers. Please download and use these Uniden signed drivers instead for Windows 8/10.
