I have been trying to install the Windows Phone 8 SDK on a Windows 8 (x86) machine. But to no avail even though I read somewhere on the site that it will install but I will not be able to run the emulator.

Is Microsoft serious that Win Phone 8 apps can only be developed on 64-bit machines?

They make it quite clear the x64 is required on the download page:

Windows 8 64-bit (x64) client versions

I can't say with any authority, but I suspect it is because the emulator uses Hyper-V, which also requires x64:

Hyper-V requires a 64-bit system that has Second Level Address Translation (SLAT).

    The latter is indeed why it's a requirement. – Claus Jørgensen Oct 31 '12 at 13:13

    I have a 64-bit processor without SLAT support and was able to install the Windows 8 Phone SDK. However, I did get an installation warning indicating that I could not use emulation. So it is possible to use the SDK and not have SLAT support. – Justin Skiles Oct 31 '12 at 16:04
  • You also need Windows 8 Professional, and not RTM. (And don't get me started on Windows RT and lack of support or tools for that shitty tablet I bought in December). – jww Apr 19 '13 at 05:51
  • I have Windows 7 Ultimate, 64 bit and I got this error message. Cannot install it. – live-love Sep 10 '13 at 14:28
