Visual Studio 2012 designer will work after updating the developer license

It happened to me twice. As soon as my developer license expires and I am asked to renew it, my visual studio designer crashes and I get the following exception when I try to load any xmal:

System.Runtime.InteropServices.COMException The application cannot be started. Try reinstalling the application to fix the problem. (Exception from HRESULT: 0x80073CFC) at 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`2 func, CancellationToken cancelToken) at Microsoft.Expression.DesignHost.Isolation.IsolatedTaskScheduler.<>c__DisplayClassa`1.<StartTask>b__6() at System.Threading.Tasks.Task`1.InnerInvoke() at System.Threading.Tasks.Task.Execute()

I tried a lot to find a solution to the problem, but nothing worked, the only way out is to install the windows again and install the visual studio again.

Something similar happened to me once. Try to clean the project, as well as clean the bin and obj folders from the project folder.

Try to clear the cache server of your visual studio and base server (if applicable). I know this sounds strange, but my team went through a very similar problem, and it was the only thing that worked sequentially (except for a complete reinstall).

Delete all files in these places:

TFS Cache: C: \ Users [UserName] \ AppData \ Local \ Microsoft \ Team Foundation [Version] \ Cache

One possible VS cache location: c: \ Users \\ AppData \ Local \ Temp \ VWDCache

Connecting a problem, which may or may not be applied, simply shows that VS is downloading cached versions of projects that potentially have conflicting license information, in your case: https://connect.microsoft.com/VisualStudio/feedback/details/758523/visual -studio-2012-reloads-a-cached-version-of-an-edited-csproj-file
