you need to make sure your PC environment was setup according to the release note:
Also, remember to run the EMDK integrator as stated in release note:
EMDK supports development of 64 bit RFID applications on Windows 7. If the 64
bit component of the Visual Studio is installed after the installation of EMDK
for C, you must run EmdkIntegrator manually using the
shortcut in the EMDK for C Start Menu program group. The EmdkIntegrator must be run with administrative rights. This
will ensure that EmdkIntegrator adds the EMDK Include
and Library files to the Microsoft SDK.
