YASM & NASM
Install YASM http://yasm.tortall.net/Download.html You want the Win32 .exe (for general use on 32-bit windows) (we don’t currently support win64 due to msvc lack of support for inline assembly) yasm-1.2.0-win32.exe Save the downloaded exe into a location you will add to the path. Rename yasm-1.2.0-win32.exe to yasm. Note: I created a Tools directory which I placed all the standalone exe’s. Just make sure to add the tools directory to the system path! Install NASM You can either install the full version from http://www.nasm.us/ -or- Copy yasm.exe and rename it nasm.exe Just make sure with either approach, nasm is available in the system path.
