For driver-related issues and those who are using Windows 7, always make sure to download this update:

Security Update for Windows 7 for x64-based Systems (KB 3033929) :/en-us/down.aspx? id=46148

This resolves the Windows signature vulnerability and will hopefully help some users still using Windows 7. Without this update, you may continue to get macro execution errors (in Device Manager, Error 52) at the prompt. Error 52 exists because Windows cannot detect our signature and therefore does not allow the driver to work. Since we always use the latest signature, your version of Windows may not be updated to reflect this and you will run into problems.
