I have been experiencing this issue for a week and tried a lot of workarounds in the internet with no results.
Here is my case: I am trying to install Windows Phone SDK 7.1 on a Windows 8 x64 host. The steps I have followed are:
- Installed Windows Games for Marketplace Client
- Installed Visual Studio 2010 and update it to Visual Studio 2010 SP1
- Installed Windows Phone SDK 7.1
- Updated SDK to Windows Phone SDK 7.1.1
- I have tried opening by using Run as administrator
None of the steps listed above returned an error. But I can't seem to run the emulator at all. The emulator list shows nothing in visual studio 2010, and when I attempt to run the emulator as a standalone application, the emulator won't run at all.
Anyone experiencing the same issue or have a workaround for this?
Thanks in advance.
PS: I got the steps above right after googling around and reinstalled the SDK and Visual Studio at least 3 times. If this is to be the issue (eg: a cleanup failed after installation), kindly advise how I proceed.
Update: I have tried installing Windows Phone SDK 8.0 with Visual Studio 2012 and the emulator still not listed in the device list.
I experienced this same issue with Visual Studio 2012 for Windows Phone. The solution was to delete the Visual Studio 11.0 user data directory, located at:
C:\Users\[user]\AppData\Local\Microsoft\Phone Tools\CoreCon\11.0
Afterwards, all virtual machines were recreated properly.
For what it's worth, I had this issue on Windows 8 under Parallels on a Mac. My Visual Studio / Hyper-V environment may have been corrupted when I put the host machine to sleep (without shutting anything down).
I still dont know what the cause of this error, but I do have a quick fix for anyone else who might be experiencing the same issue.
The fix for me was to use a new windows profile. (No need to reinstall the application) Just create a new windows profile and use that one.
why are you using the Visual studio 2010 when visual studio 2011 is already present there with windows phone 8 sdk with all the windows phone 7 feature included . May be some emulator for windows phone 7 sdk is not supported on win 8 machine. Try reinstalling the sdk , it will resolve the issues.
