Answer 1

You've probably chosen VC-WIN64I (as an argument for the perl Configure command), which is a wrong platform in your case. You should have passed VC-WIN64A. "I" stands for "Itanium" and "A" still stands "AMD64".

Run

perl Configure VC-WIN64A

and then run "nmake" again, it should work this time.
