Briefly: - Mathematica runs fine under the 64-bit version of Windows Vista - The Mathematica frontend (32-bit and 64-bit) has no problem running under Vista 64-bit - A 64-bit operating system is required to take advantage of the 64-bit enabled Mathematica kernel (or any 64-bit program) In more detail: The Windows version of Mathematica 6.0 contains 32-bit (x86) and 64-bit (x86-64) versions of both the frontend and kernel binaries. The Mathematica 6.0 installer installs the 32-bit versions when run on a 32-bit system and the 64-bit versions when run on a 64-bit system. The 32-bit versions of the kernel and the frontend will run on Vista x64, though usually one would run the 64-bit version of Mathematica with a 64-bit operating system, since that it what is installed by the Mathematica installer. Running 32-bit programs is a feature provided by Vista x64. 32-bit programs can communicate with 64-bit programs. The 64-bit versions of the kernel and the frontend will not run on 32-bit Vista. 32-bit Vista can't run 64-bit programs. (In the older Mathematica 5.2 for Windows, the frontend was 32-bit only and the kernel was either 32-bit or 64-bit, depending on the version of Windows. The 32-bit frontend is capable of communicating with a 64-bit kernel, which was the expected scenario on a 64-bit Windows machine.) Chris Hill Wolfram Research
