USB Driver Installation Errors - Code 52 & vendor.cer

With the release of N2KAnalyzer 3.0.4 we introduced a new USB driver that provided better support for Windows Operating Systems 7 - 11 for 32-bit and 64-bit architectures.


The following errors may occur on Windows 7, 8, 8.1 installations while updating the USB driver to version 2.15.


Code 52




File(s) 'vendro.cer' not found in 'C:\Program Files\CarlingTech\USBCOM Driver'.


This is due to an outdated/missing security update for the Windows Operating System.


Please download and install the following Microsoft Security Update: KB3033929


Once the update is installed, please install the latest Maretron USB Driver.


If you continue to experience any issues please contact Maretron Support at (866) 550-9100 or via email at
