Issue:Windows 7 x64 users may experience an error when attempting to install the most current version of wtfast. This OS requires all drivers to be digitally signed. In the same time the old (non-updated) versions of Windows 7 does not support SHA-2 (aka SHA256) certificates for kernel drivers.

Resolution: Ensure that the windows OS is fully updated. Or please visit the microsoft link below to install the required update separately. 

Windows 7 and Windows Server 2008 R2 require kb 3033929 to validate SHA-2 signed kernel drivers.
