Visual Studio 2013 Premium solution load errors after Update 3 - azure

Question

I installed VS2013Update 3 and now I get errors when opening an solution:
The 'Microsoft.VisualStudio.Web.Publish.WebPublishPackage,MircosoftVisualStudio.Web.Publish' package did not load correctly.
And
The 'ScaffoldungVSPackage' package did not load correctly.
The outcome of this is that I can't open the Publish-Dialog and there are no templates when creating a new Webproject.
In the activitylog are following errors:

Has anyone an idea how to resolve this issue? I already tried:
Reinstalling VS2013
Reinstallung Update 3
Reinstalling WindowsAzureSDK V2.4
Disabling Extensions
run /devenv setup /devenv updateconfiguration
Delete Appdatafiles
Thanks!

Answer 1

the following solution from the asp.net-forums worked for me:
the solution was to reset the assemblies for Contract and Publishing using the Developer command prompt as Administrator If you have used the default installation setting then this is probably the path
gacutil -i "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\Extensions\Microsoft\Web Tools\Publish\Microsoft.VisualStudio.Web.Publish.dll"
gacutil -i "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\Extensions\Microsoft\Web Tools\Publish\Microsoft.VisualStudio.Web.Internal.Contracts.dll"

Answer 2

I resolved the issue by downloading the assemblies and restarting VS2013 update 5
