更新3后的Visual Studio 2013 premium解决方案加载错误

我安装VS2013Update 3，现在我得到打开一个解决方案时错误：

I installed VS2013Update 3 and now I get errors when opening an solution:

在'Microsoft.VisualStudio.Web.Publish.WebPublishPackage，MircosoftVisu​​alStudio.Web.Publish'包未正确加载。

The 'Microsoft.VisualStudio.Web.Publish.WebPublishPackage,MircosoftVisualStudio.Web.Publish' package did not load correctly.

和

在'ScaffoldungVSPackage'包未正确加载。

The 'ScaffoldungVSPackage' package did not load correctly.

这样做的结果是，我无法打开发布，对话，创造一个新的Webproject当没有模板。

The outcome of this is that I can't open the Publish-Dialog and there are no templates when creating a new Webproject.

在activitylog是以下错误：

In the activitylog are following errors:

有没有人一个想法如何解决这个问题？我已经尝试过：

Has anyone an idea how to resolve this issue? I already tried:

• 重新安装VS2013


• Reinstallung更新3


• 重新安装WindowsAzureSDK V2.4


• 禁用扩展


• 运行/ devenv的设置/ devenv的updateconfiguration


• 删除Appdatafiles

谢谢！
