You don't need to worry about Intel64. You don't have one. Neither do your
customers. Intel64 refers to the Itanium processor family, not Core or Xeon
processors, which come under x64. It's badly named but for historical
reasons - Intel produced Itanium processors, referred to as IA-64 for Intel
Architecture, 64-bit, several years before AMD extended the x86 instruction
set to 64 bits.
(Itaniums are very rare and expensive. Architecturally they're superior if
you're starting from a clean slate and comparing clock-for-clock, but as
x86/x64 clock speeds have ramped up they're faster for less money. Itanium
still has the edge on floating-point performance of native Itanium code, but
is still pretty poor - despite JIT-compiling x86 code - on 32-bit code.)

Is it possible to have one installer, that recognizes whether the OS is 64
bit or not. Then installs either the 64 bit or the 32 bit version of our
software accordingly? Or do we have to have two separate installers, one to
install the 32 bit version, and another for the 64 bit version?
You need two. MSI, for whatever reason, doesn't allow multi-platform or
platform-neutral packages.
>From what I've read, you have to set x64 or intel64 in the installer for 64
bit. What if you don't know at compile time what type of processor is being
used?
If you support both IA64 and X64, you need two packages (three if you also
support X86).
