The \System Root\System32\drivers\NatMotion.sys device could not locate the entry point IoSetDeviceInterfaceState in driver ntoskernal.exe

After installing version 5.1.1 of the Flexmotion driver, and installing f5 update, I got the following message after rebooting the system: The \System Root\System32\drivers\NatMotion.sys device could not locate the entry point IoSetDeviceInterfaceState in driver ntoskernal.exe. OS is Win NT. I see device in MAX , but can not initialise it, and cannot make firmware update.
I do not se device from NT system menager.

The instructions on the f5 update are not 100% explicit about what to do for NT. The NatMotion.sys file should not be replaced on NT systems, only on the specifically listed OSes. Uninstall and reinstall the 5.1.1 driver along with the f5 update, however only install the components that do not specifically mention a particular OS.
