"intel 64bit" is as clear as mud. It could mean the "Intel 64"
architecture, or it could mean the "IA-64" architecture, both
are 64-bit architectures with processors manufactured by Intel.
The former is officially called AMD64 (not by Intel, but
officially), and our AMD64 binaries run on such processors.
The latter is also called "Itanium", and we stopped producing
binaries for that architecture a while ago; the AMD64 binaries
will *not* run on it.
The wording could probably be changed to match the reader's
expectation more, most likely, it would also get more incorrect
in the process. To make it correct and explicit, an entire
paragraph educating users about 64-bit architectures and that
there are many of them and that they are mutually incompatible
might be required.
Most likely, Thomas' processor implements the AMD64 architecture,
even though it is manufactured by Intel. A short sentence that
he would probably understand (given that he used "Intel 64", not
"""The binaries for AMD64 will also work on processors that implement
the Intel 64 architecture (formerly EM64T), i.e. the architecture that
Microsoft calls x64, and AMD called x86-64 before calling it AMD64.
They will not work on Intel Itanium Processors (formerly IA-64)."""
