This is working for me even though it is not endorsed or supported officially by Microsoft.

<blockquote>
 Mike Harder (Microsoft) commented · January 31, 2013 5:26 p.m.
 
 You can configure Visual Studio 2012 to use IIS Express 64-bit by
 setting the following registry key:
 
 reg add
 HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0\WebProjects /v
 Use64BitIISExpress /t REG_DWORD /d 1
 
 However, this feature is not supported and has not been fully tested
 by Microsoft. Improved support for IIS Express 64-bit is under
 consideration for the next release of Visual Studio.

Late to the party but VS2013 has this in the Options.

You have to launch iisexpress from command line in this case,

As I am not sure when will Microsoft updates the VS integration part to allow you to choose x64 IIS Express. The current integration obviously is x86 only.

It seems that creating EXE that does nothing else but start 64-bit IIS and putting it in place of 32-bit <code>iisexpress.exe</code> does the job.

This is C# code I used to create the EXE:

<pre><code>using System.Diagnostics;

namespace IISExpress64

 static void Main( string[] args )
 {
 Process.Start( @"C:\Program Files\IIS Express\iisexpress.exe", string.Join( " ", args ) );

In order to solve this on my system, I cheated -- I copied the 64-bit executables (in <code>\Program Files\IIS Express\</code>) over the 32-bit executables (in <code>\Program Files (x86)\IIS Express\</code>). Visual Studio doesn't seem to care whether it's one or the other.

I guess we will have to wait and see if the final release of VS 2012 will allow for choosing between the 32-bit and 64-bit IIS Express.

on x64 Windows 7 I am trying to get hello world MVC 3 website running as 64-bit process (so Environment.Is64BitProcess returns true on a page) using IIS Express 8 latest beta. 

IIS Express 7.5 is 32 bit but IIS Express 8 does support 64 bit (<a href="http://learn.iis.net/page.aspx/1266/iis-80-express-beta-readme/" rel="noreferrer">http://learn.iis.net/page.aspx/1266/iis-80-express-beta-readme/</a>). 

Can't get any 64-bit love. 

Building AnyCpu returns Is64BitProcess false, building x64 gives "An attempt was made to load a program with an incorrect format. " as if it was trying to run as 32-bit process. 

Experiments w/ renaming folders etc. suggest that "C:\Program Files (x86)\IIS Express" is only thing that is getting used, and "C:\Program Files\IIS Express" is being ignored by VS. 

How can I get VS to use the x64 IIS Express host?
