C/Invoke is another library whose name i forget.

i don't know, just read yesterday on Lua list:

I can answer part of that. Libffi  (the C library on top of which
Alien is built) has no support for 64-bit windows. More specifically
there is a need for some runtime generated glue code (mainly for
callbacks), and assembler support for x64 is very poor so far (many
Visual C++ compilers come without assembler and/or lack support for
Python and Java (in the JNA package) have their own port of libffi
specifically for x64. However I never managed to compile any of these
two for Alien (usually because of the lack of assembler).
I tried all this about a year ago, so things may have changed since then.
