My own experience with this error:
I tried reinstalling for 100 s of time and finally got the solution by following the below procedure.
- Installed fresh Windows 8 OS
- Update Windows to up to date ( Update can solve most issues in my experience)
- Now install Visual Studio 2012 Ultimate in your system.
- Now install the WP 8 SDK .It works fine for me
Try installing Direct installation rather than using ISO for WP 8 SDk:
Follow the same three steps above and now go to Visual Studio ultimate and resgister with your credentials from Microsoft or you can continue the 90 day trial pack from Microsoft.
Now open Visual Studio 2012 Ultimate and click on New project --> Windows Phone in installed template and now click download Windows Phone 8 SDK. You will seen the installation directly starts but need internet got online installation.
Hope your errors solved
