Windows 64 bit (Vista and after) - FYI
A new "security feature" in Windows prevents installing and loading of drivers that have not been signed by Microsoft. If you have a 64bit operating system, Vista or newer, you will have to follow special procedures to install and use the included drivers. If signed drivers exist they will be added to the download when they are found.
Before you installed the drivers and whenever you want to use the ADB / Odin functionality later you must do the following:
Reboot your computer, once it begins starting immediately hold F8.
After a few seconds you will get the Windows Startup Menu.
Select "Disable Driver Signature Enforcement".
Install or use your driver/device in Windows.
