- 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
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
