Had a customer who a opened a ticket for help on this error. The project built fine on Windows 8 but after upgrading to Windows 8.1 he started seeing above error on compilation using a 64 bit toolset.
After much troubleshooting we found the issue to be caused by a pre-release version of WDK installed on his machine. RCToolPath pointed to an older version of WDK8.1.
Customer uninstalled pre-release of WDK (to be precise: Windows Driver Kit for Windows 8.1 Preview) and installed WDK RTM. This resolved the tracker error in this case.
