FAQ #2.15:

After having installed the hardware security key drivers (version 7.2.1) on a Sony Smart Camera, I try to run either VisionGauge® or VisionGauge® OnLine and I get an error message about the "SNTNLUSB.SYS" file.

Solution:

This problem occurs when the the installer for the hardware security key drivers is unable to properly install this file on the Sony Smart Camera. To correct the problem, simply download this "SNTNLUSB.SYS" file and copy it to the camera's "C:\WINDOWS\System32\drivers" sub-directory.
