Estoy en el medio del desarrollo de aplicaciones de la Tienda Windows. De repente se produjo una excepción cuando abro el archivo XAML
"System.Runtime.InteropServices.COMException.
La aplicación no se puede iniciar. Intente volver a instalar la aplicación para solucionar el problema. (Excepción de HRESULT: 0x80073CFC) "

Lo que intenté hasta ahora:

1. Reinicie PC
2. Reinstalar Visual Studio 2012 ultimate
3. Desinstale VS 2012 ultimate e instale VS2012 Express para Windows 8.

Pero aun así el error es igual.

Los detalles del error son:Microsoft.Expression.HostUtility.AppPackage.AppPackageNativeMethods.IApplicationActivationManager.ActivateApplication(String appUserModelId, String activationContext, ActivateOptions options, Int32& processId) at Microsoft.Expression.HostUtility.AppPackage.WrtUtility.ActivateApplication(String appUserModelId, String activationContext, Object site) at Microsoft.Expression.HostUtility.Platform.AppContainerProcessDomainFactory.ActivateApplicationInternal(String appUserModelId, String activationContext, Object site) at Microsoft.Expression.HostUtility.Platform.AppContainerProcessDomainFactory.CreateDesignerProcess(String applicationPath, String clientPort, Uri hostUri, IDictionary environmentVariables, Int32& processId, Object& processData) at Microsoft.Expression.DesignHost.Isolation.Primitives.ProcessDomainFactory.ProcessIsolationDomain..ctor(ProcessDomainFactory factory, IIsolationBoundary boundary, AppDomainSetup appDomainInfo, FrameworkName targetFramework, String identifier, String baseDirectory) at Microsoft.Expression.DesignHost.Isolation.Primitives.ProcessDomainFactory.CreateIsolationDomain(IIsolationBoundary boundary) at Microsoft.Expression.HostUtility.Platform.AppContainerProcessDomainFactory.CreateIsolationDomain(IIsolationBoundary boundary) at Microsoft.Expression.DesignHost.Isolation.Primitives.IsolationBoundary.Initialize() at Microsoft.Expression.DesignHost.Isolation.Primitives.IsolationBoundary.CreateInstance[T](Type type) at Microsoft.Expression.DesignHost.Isolation.IsolatedExportProvider.Initialize() at Microsoft.VisualStudio.ExpressionHost.Services.VSIsolationService.CreateExportProvider(IIsolationTarget isolationTarget, ICatalogFactory catalogFactory, IExportFilter filter) at Microsoft.Expression.DesignHost.Isolation.IsolationService.CreateLease(IIsolationTarget isolationTarget) at Microsoft.Expression.DesignHost.IsolatedDesignerService.CreateLease(IIsolationTarget isolationTarget, CancellationToken cancelToken, DesignerServiceEntry& entry) at Microsoft.Expression.DesignHost.IsolatedDesignerService.IsolatedDesignerView.CreateDesignerViewInfo(CancellationToken cancelToken) at Microsoft.Expression.DesignHost.Isolation.IsolatedTaskScheduler.InvokeWithCulture[T](CultureInfo culture, Func<code>2 func, CancellationToken cancelToken) at Microsoft.Expression.DesignHost.Isolation.IsolatedTaskScheduler.<>c__DisplayClassa</code>1.b__6() at System.Threading.Tasks.Task`1.InnerInvoke() at System.Threading.Tasks.Task.Execute()
