In versions of Windows 7 with patches after January 1, 2016 the operating system will complain that the driver has not been digitally signed as shown below. A signed Driver Error. While the driver has been digitally signed, it was signed with a SHA1 certificate which has now been deprecated by Microsoft for applications released after January 1, 2016.
To solve this problem please download version 1.0.4 or later from:

This edition includes a driver signed with a SHA256 certificate and will work without this error. Please ensure you have first uninstalled the existing version and then reboot your machine before reinstalling the new version. Â This will ensure the older driver is not interfering with the new one.
