OS detection will be used in conjunection with the MSI Template summary property of the MSI package embedded in the native executable to present a more user-friendly error message if a user accidentally downloads and tries installing a 64-bit patch on a 32-bit system. To decrease patch size and present a better end-user experience, we are looking to implement a 32-bit native wrapper for all three architectures. While normally x86 code would run under WOW64 on 64-bit systems, the 32-bit release setups and patches will block on 64-bit systems (at the time this was published) to make sure that both 32- and 64-bit binaries are present. The latter two patches will contain both 32- and 64-bit binaries for the reasons given above and will be larger in size. So patches need to come in three flavors: x86, ia64, and 圆4. There are flavors of both Windows XP and Windows Server 2003 that currently run on 圆4 which is poised to become the predominant 64-bit computer technology it would seem. X64 is the term Microsoft uses to collectively refer to processors that run both 32- and 64-bit code natively without emulation – both AMD64 and EM64T. This processor also supports running 32-bit processes natively like the AMD64. Intel has also introduced EM64T – or Extended Memory 64 Technolocy – for Intel Xeon processors. You need to run Windows Server 2003 for 64-bit Itanium-based Systems. IA64 – or Intel Itanium – processors run 64-bit natively and offer 32-bit emulation, but you cannot install 32-bit Windows on it. These machines have already begun shipping with 32-bit Windows XP and a friend of mine in MN is already running one happily. This means that you can install 32-bit Windows on an AMD64 machine. AMD64 is Advanced Micro Devices, Inc.’s answer to 64-bit computing that runs 32-bit code natively as well. So what is difference between x86, AMD64, IA64, and 圆4? x86 is what most everyone is running now – 32-bit processes on 32-bit Windows. Future versions should, by the way, should replace “AMD64” with “圆4”. NET 2.0 installed and look in %windir%assembly you’ll see a new column in the shell view that tells you if the assembly is MSIL, x86, or AMD64 or IA64. For code running natively under 64-bit Windows, access to 64-bit assemblies is necessary. Because 32-bit code will run under 64-bit Windows under Windows-on-Windows 64 (WOW64) 32-bit processes still may need access to the 32-bit assemblies either in the GAC or in the Framework version directory (ex: %windir%Microsoft.NETFrameworkv2.0.nnnn). In these cases both 32- and 64-bit assemblies are required. NET Framework need to support 64-bit platforms, though? While most IL modules embedded in assemblies – which are still PE/COFF executables – are architecturally agnostic some are not, like CustomMarshalers.dll or mscorelib.dll. It’s been quite an adventure down the yellow-brick road of 64 bitness that I think is worth sharing. NET Framework 2.0 now supporting 64-bit platforms, I have begun work on upgrading our patch build system to handle 64-bit patches. The x in x86 represents 1, 2, 3, etc.With the. Those are names Intel assigned to their CPUs. The CPUs that are the predecessors of the current CPUs in most "Personal Computers" (PCs) has its origins with the first Intel CPU, the 4004. Looking at the history of Intel CPUs, it's fairly easy to trace the origins of names like i686. x86_64 is a 64 bit CPU architecture that "includes" 32 bit capability for the sake of "backwards compatibility". ![]() X86_64 refers to a CPU design that is based on a 64 bit architecture (see )Įssentially i686 is the 32-bit component of x86_64 and represents the x86 part of the x86_64 name. I686 refers to a CPU design that is based on a 32 bit architecture (see ) In answer to your question: x86_64 is not the same as i686, however x86_64 "includes" i686 capability. : libraries, as well as national language (locale) support.
