; libs
includelib VMProtectSDK64.lib

This header file for x64 is missing from VMProtect official SDK /Include/ASM/VMProtectSDK.inc
VMProtect only provide 64bit version for C. This is tested and worked on Visual Studio 2013, 2015

The difference between VMProtectSDK64.inc and original VMProtectSDK.inc are:
WCHAR[256] -> WORD[256]
includelib VMProtectSDK32.lib -> includelib VMProtectSDK64.lib
