Windows Phone 8 Emulator Compatibility Issue in Windows 8.1 Preview

Hello and yes we will again resolved an issue for you. I have come to understand that after installing Windows 8.1 Preview, it gives a compatibility issue with SDK 8.0.  In the result Windows Phone 8 Emulators does not run and give a pointer error, basically that is due to the very problem of compatibility.

How can we resolve it?

How can one run Windows Phone 8 Emulators on Windows 8.1 Preview?

If you run it after ignoring it, you will find that the Windows Phone 8 Emulator does not work.
 
You can resolve it by installing Update 3 of Visual Studio.
 
Here you go.
 
Download Link Update3 VS

The story does not end here. Even after installing VS Update 3 you may get this error.

HRESULT: 0x89721800

Well if this occurs you would not be able to run any emulator and at device selection START will be displayed only.
 
There are two solutions for resolving it,

The only hint I found is the following: WP7 Deployment Error Codes Explained.

If you get the error code 0×89721800 when attempting to deploy to your phone device, this typically indicates that the Visual Studio datastore is corrupt. Here are a couple of workarounds.
 
Workaround 1

  1. Close all Visual Studio instances that may be currently running.
  2. Delete the folder “%LOCALAPPDATA%\Microsoft\Phone Tools\CoreCon\10.0”
  3. Launch a new instance of Visual Studio

Workaround 2

The above error code has also been reported when Windows Mobile 5x or 6x emulators are installed in the system. Try uninstalling them both.

  • So I would give this a try, clean out all the folders under LOCALAPPDATA%\Microsoft\Phone Tools\CoreCon.
  • If that does not help then uninstall the SDKs and reinstall the latest one for WP 8.

Further the following link points to other (WP8) Emulator (XDE) Troubleshooting Tips.

  • Alternative Workaround.
  • Open File Explorer.
  • Open this path: %LOCALAPPDATA%\Microsoft\Phone Tools\CoreCon\
  • Now delete 10.0 and 11 named folders and others from this path.

Note: Before doing the entire procedure close all instances of Visual Studio.

Let us know if that helps you to get the 7.x / 8.0 emulator working on your dev PC.
