Grab the 64-bit binaries (ML64.exe, link.exe)

[jj2007]

In order to use the original Masm64 SDK, you need the ML64 and link binaries. Here is a program that allows to install them from known Microsoft locations. Extract all files to a folder on your Masm drive, then run GrabBin64.exe.

The smallprint:
Use at your own risk. The downloads may be copyrighted, or you may need a Visual Studio license to use them.
