Under Windows 10 the J-Link installer will successfully install the driver for J-Trace/J-Trace Pro. However under some circumstances the driver will be loaded and cannot be put into functional state.

Windows claims that the USB device is not recognized.

Using the DeviceManager to look at the J-Trace Device Properties shows that the driver code not be started (Code 10).An additional error message says that a device which does not exist was specified.
