Have you tried exactly the code I provided?  "Almost the same" 
is a usual difference between working and non-working code.

Works fine at least in Windows 7 and Windows 8.1 VMs here, both 
32-bit.  I have no 64-bit Windows on hand to test, but if it 
doesn't work for you specifically on 64-bit Windows, this may be 
some minor bug in the test code related to type casting.
