--- Comment #2 from François Gouget  ---
w1064v1507 does not support SystemSupportedProcessorArchitectures() which
causes the test to be skipped (and RtlWow64IsWowGuestMachineSupported() is
missing too).
So w1064v1607 is the first version (we have) where this test can be run. Maybe
that first implementation was buggy. Adding some traces shows that we get the
expected results from the other APIs:

w1064v1607 wow64.c:207: native_machine=34404 status=0 ret=0
w1064v1709 wow64.c:207: native_machine=34404 status=0 ret=1

I also compared the w1064v1607 VM configuration to the w1064v1709 one and there
is absolutely no difference. So it's not an issue with the processor model or
something like that.
