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 Visual Studio 2013 Professional, and I got the same error. I couldn't remove it until I repaired the Visual Studio installation. It took a while, but now it works fine.

Answer 2

Updating Visual Studio 2017 through the Visual Studio installer fixed the problem for me.

Answer 3

You need to find file devenv.exe.config in C:\Users\{user_name}\AppData\Local\Microsoft\VisualStudio\14.0\ and update it. (Or C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\, depending on the location of your devenv.exe file.)

For this particular case, you should find rows that setup redirects for System.Collections.Immutable and change newVersion from 1.1.36.0 to 1.1.37.0.
