What's the meaning of IA-32, IA-64? When I installed the Intel Fortran, I selected all three, so all of those installed into my 32 bit xp. Do I need to install only IA-32? If I need to update software, which one I need to download for 32 bit xp?


Also after I delete my old Compaq Fortran 6.6c, and installed Intel Fortran. Another software called Mingw studio can't run my code, it reported "The instruction at "0x7c911e58" referenced memory at "0x00270020". The memory could not be "read"".
After install Intel Fortran, will some part of it stay in the memory even I don't run the code? Thank you!

Only the IA-32 compiler will make code to run under 32-bit Windows. IA-64 code will run only on Itanium, Intel64 will run under Windows X64 OS. Since ifort 10.0, the compilers for each architecture are available as separate downloads.
Installing Intel compilers has no impact on mingw programs, unless something is broken in your PATH environment settings, but that doesn't appear to be the cause of the error you mention. The 64-bit compilers will occupy disk space, and you may as well remove them.

Short description

IA-32 = Intel Archetecture 32-bit. e.g. Pentium in 32-bit
IA-64 = Intel Archetucture 64-bit e.g. Itanium 64-bit (not Pentium in 64-bit)
Intel 64 = EM64T = IA-32 with 64-bit extensions e.g. Pentium in 64-bit

You may only need the IA-32 for your 32-bit XP system.

Have you consider upgrading to 64-bit XP?

On the cheap you could go

Pentium D 925 3.0GHz Dual Core ~$100
LGA 775 motherboard ~$100
4GB DDR RAM ~$100
Windows XPx64 ~$??

If you have a little more pocket change you could choose a better processor (Qad Core, or Core 2 Duo)

Don't know anything about Mingw Studio

I already have core 2 duo machine with xp 32bit. I will uninstall Intel Fortran to see what caused the Mingw studio problem.

Intel need to improve the install program. I selected custom install, it can install three edition into my xp 32 bit machine.

Please read the Installation Guide which is available as a link from the initial install page or can be downloaded alongside the installer. It explains all of this.
