• In Visual C++ 2008 32-bit Command Prompt:

set PATH=C:\Users\IEUser\AppData\Local\nasm;%PATH% perl Configure VC-WIN32 --prefix=C:\OpenSSL-Win32 ms\do_nasm nmake -f ms\ntdll.mak nmake -f ms\ntdll.mak test nmake -f ms\ntdll.mak install

Precompiled

There are precompiled but need to ensure the compiler is msvc 9.0 (2008) along with the openssl include and lib folders for libtorrent to link to.
