Featured information: Windows App Certification Kit; Windows Software Development Kit (SDK) for Windows 8; Download Visual Studio 2012 Update 4; The Visual Studio 2012 Shell (Isolated) Redistributable Package contains the run-time binaries that are required to deploy an application that's based on the Visual Studio 2012 Shell (Isolated); Disable Program Compatibility Assistant in Windows 7 and Vista.

I have made a modified installer for the Windows Phone 8 SDK that will run on Windows 7 x64. I installed visual studio before I installed the SDK, but it shouldn't matter as this will install visual studio express for windows phone, if needed.

To install the SDK, perform the following:

1. Download the Windows Phone 8 SDK iso file. You can get it at this LINK
2. extract the contents of the ISO to the location of your choosing.
3. Download the modified "WPexpress_full.exe" that is attached to this post and use it to replace the one in the iso.
4. run setup as normal.

Everything will install and work.*
*I was getting an error when I launched the "Application Deployment" app. Once I updated Visual Studio 2012 to Update 3, it fixed it. EVERYTHING WORKS!!

Just wanted to add everything works 100%...I was able to recompile and deploy some xaps I wrote on my win 8 PC to my phone with no issues!

N.B. from TurismoAssociati:

Here is the LINK for the Visual Studio 2012 Update 4 (number 3 was updated)

You might, as we did, encounter two error messages that will stop the installation:

- Windows Software Development Kit Tools for Windows Store file sdksetup missing. LINK HERE for the download page.

- Microsoft Visual Studio 2012 Shell (Minimum) Vs_isoshell.exe Isolated missing. LINK HERE for instalation file.

You might need to Disable Program Compatibility Assistant in Windows 7 and Vista LINK HERE.

Before you submit your app for certification and listing in the Windows Store, use the Windows App Certification Kit to test your app and make sure it's ready to go. Here is the LINK with the solution.

P.S. Very important: Visual Studio 2012 will fail to install after October 7, 2013

When you try to install Visual Studio 2012 after October 7, 2013, you receive one of the following error messages:
Unable to locate package source

Microsoft Web Deploy 3.0
A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file.

WE CHANGED THE DATE AND TIME ON OUR MACHINE TO A PREVIOUS DAY BEFORE OCTOBER 2013, AND THE INSTALLATION WORKED!
