NuGet fails to load after updating to Visual Studio Update 3

After updating to Visual Studio Update 3 (I was previously running Update 2), NuGet fails to load. By that I mean the Package Manager no longer shows up after I have loaded a solution that uses NuGet and used to work.
  • It does not show up under the Tools Menu.
  • NuGet (Manage NuGet Packages) does not show up in the menu after right click on the solution
  • NuGet (Manage NuGet Packages) does not show up in the menu after right click on the project
The Extensions and Updates dialog (TOOLS/Extensions and Updates...) does show the NuGet Package Manager as installed and when I click on it it shows that it can be uninstalled.

Also when I checked the installation log after uninstalling and then re-installing the NuGet Package Manager (from the download I got on the CodePlex nuget site) it shows that it was successfully installed:

/10/2013 11:39:05 AM - Beginning to install extension to Microsoft Visual Studio Professional 2012...
7/10/2013 11:39:05 AM - Install to Microsoft Visual Studio Professional 2012 completed successfully. The extension has been installed to C:\PROGRAM FILES (X86)\MICROSOFT VISUAL STUDIO 11.0\COMMON7\IDE\EXTENSIONS\VYALGTD2.XZS\

I checked and this folder does in fact exist and contains NuGet dlls.

When I go to the TOOLS/Options... dialog and select Package Manager the right hand pane shows the text: "An error occurred loading this property page". The same text is shown when Package Manager is expanded and either General or Package Sources are selected.

I have uninstalled and re-installed NuGet numerous times and I have installed both from the downloaded VSIX and directly in the Extensions and Updates dialog and the result is always the same.

I have installed an older version of NuGet and I get the same results. I have uninstalled Visual Studio and re-installed it and I get the same results with version 1, Update 2, or Update 3.

The Activity.log.xml file shows the following issue when attempting to load NuGet:

This part looks OK. But then there are the following warnings and errors:

With the main clue being in record 246 --
__<errorinfo>Could not load file or assembly 'NuGet.Tools, Version=2.6.40627.9000, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.</errorinfo>__

The question is why can't the system find the file or what dependency is missing. MSDN Tech support was helping me, but then decided that this was a problem they would not support and that I should post the issue here.

Well I fixed this problem by doing the following:
  1. Uninstall Visual Studio 2012 (Control Panel - Program and Features - Microsoft Visual Studio Professional 2012)
  2. Delete the VS 2012 folders under Program Files and Program Files(x86). The actual name is Microsoft Visual Studio 11.0 (Very Poor that the uninstall does not remove the folders).
  3. Remove VS 2012 entries from Registry HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE (These will be the 11.0 entries under Visual Studio)
  4. Re-install Visual Studio 2012 (I get my version from an MSDN subscription download)
This fixed the problem I had with the Package Manager but I am left with a different problem where Web.Mvc.Package.MvcPackage does not load correctly and then my Solution will not longer recognize the project file for a solution I have because it indicates that it is incompatible. So I am back to uninstalling and removing all entries under Visual Studio 2012 (folders and registry) pertaining to MVC 4 and then re-installing again.

I am having the same issue. When I start Visual Studio 2012 I get the message "EurekaPackage failed to load" or something to that effect. I am having the same exact problems as you to a tee. I had these issues when I updated to Update 2, but instead of dealing with their crap I uninstalled and didn't use update 2. I now have to update Visual Studio and am stuck dealing with this. I think I'm just going to re-install windows. I spend days trying to fix it before to no avail.
