How can I fix the Microsoft Visual Studio error: “

Question

I installed Visual Studio 2012 and DevExpress 13.1. As Visual Studio started, it generated an error shown by this attached image,

The 'Microsoft.VisualStudio.Editor.Implementation.EditorPackage' package did not load correctly.

The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file 'C:\Users\must\AppData\Roaming\Microsoft\VisualStudio\11.0\ActivityLog.xml'.

Continue to show this error message?

This error also appears in Visual Studio 2017.

Answer 1

I had the pleasure of experiencing this random problem in Visual Studio 2017 Enterprise.

I tried every solution here, and it didn't work, including the Visual Studio repair (which takes a while). Several hours in, I thought maybe I should actually check the ActivityLog.xml file.

I uninstalled the offending extension from the 'Developer Command Prompt for VS2017' as an administrator since Visual Studio just freezed after open and nothing could be clicked.

Steps to uninstall - courtesy of jessehouwing.net

1. Find the vsix file you used to install the extension.
2. Open it in your favorite archiver (mine is 7-Zip).
3. Grab the extension's Id from the Identity node from the extension.vsixmanifest.
4. Run (in my case) vsixinstaller /u:Microsoft.VisualStudio.LiveShare to remove the extension.

Answer 2

I had this problem, and projects were not loading correctly or stating that they needed migration. The ActivityLog.xml showed an error with a particular extension. I uninstalled the extension and restarted Visual Studio. That resolved the issue.

Try devenv /setup on the Visual Studio Command Prompt with administrative rights.

I had the same problem with Visual Studio 2013 Ultimate. I tried the solution by Reza posted here, but it didn't work.

Eventually I couldn't close Visual Studio. It was showing a similar dialog when I tried to close, and it wasn't closing. I tried this: Error message "No exports were found that match the constraint contract name". Neither.

I noticed a message in the Team Explorer window saying "Page 'somenumber' cannot be found". I tried that way, and I found this answer: Page '312e8a59-2712-48a1-863e-0ef4e67961fc' not found using Visual Studio 2012. So I run devenv /setup on the Visual Studio Command Prompt with administrative rights.

It did the job, and everything is fine now.

I also had this issue with Visual Studio 2013 update 4. After running the update 4 installer again and choosing Repair, then restarting the machine, the issue went away.

Solution for Visual Studio 2017:

Step 1: open Visual Studio cmd in administrator mode (see start menu item: Developer Command Prompt for VS 2017 - Be sure to use: Run as administrator)

Step 2: change directory to the folder where Visual Studio 2017 is installed, for example:

cd C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise

(You can copy/paste this command to your cmd prompt. For Visual Studio Professional, the folder will be called "Professional" instead of "Enterprise", etc.)

Step 3: copy/paste the below command

gacutil -if Common7\IDE\PublicAssemblies\Microsoft.VisualStudio.Shell.Interop.8.0.dll

Hit Enter...

It will resolve the issue...

Otherwise, you can also add the following to the GAC as above:

Microsoft.VisualStudio.Shell.Interop.9.0.dll

Microsoft.VisualStudio.Shell.Interop.10.0.dll

Microsoft.VisualStudio.Shell.Interop.11.0.dll

Answer 6

I got the same issue, in Visual Studio 2015. After spending hours from my day, I found an answer for this:

• Close all your Visual Studio instances
• And go to {AppData\Roaming\Microsoft\VisualStudio\14.0}. Clear the things inside it.
• Start Visual Studio in administrator mode. It will repair the folders inside it.
