Installing Visual Studio 2015 Update 1 give me lots of : “package did not load correctly”

问题

I installed VS2015 with update 1 on Windows 7 Entreprise English over Visual Studio 2015. The setup result was some error(s). I Restarted my machine and run the setup again. The setup completed successfully.

Note: that I had Resharper installed on first setup and I removed before retry the setup for the second time (which succeeded).

After re-installation, I got many message box with "package did not load correctly".

Example:

Now my visual Studio 2015 with Update 1 is totally upside down??? I got error message on start (package did not load correctly):

• Python Tools Package
• XamarinShellPackage

And many more when loading a project (package did not load correctly):

• CollaborationPackage
• ...

Any idea on how we can solve that problem???

Update: I'm trying now to uninstall and then re-install again with Visual Studio 2015 with Update 1...

I fixed my problem by uninstalling Visual Studio 2015 completely and re-install VS2015 with Update 1.

I found this, maybe that can solve your problem:

Packages not loading after installing visual studio 2015 RTM

By Shittu Joseph Olugbenga

All i did to get it working was to follow this step: 1.Close all instances of Visual Studio 2.Delete everything in this folder C:\Users\\AppData\Local\Microsoft\VisualStudio\12.0\ComponentModelCache 3.Restart Visual Studio

Though I have not tried this for 2015, I believe this should solve the problem too. To do this for visual studio 2015, 12.0 should be changed to 14.0

I had to do a combination of the other answers, none of which was uninstalling VS

1. I renamed C:\Users\{User}\AppData\Local\Microsoft\VisualStudio\14.0
2. started VS2015
3. closed it down
4. did the binding redirect for System.Collections.Immutable from https://stackoverflow.com/a/34018770/57883

Then I've been copying the extensions I think are safe over and seeing if projects all still load.

Try restarting the computer. It was what fixed the issue for me (which appeared right after modifying my installation, and I had not restarted the computer).

回答5:

Close Visual Studio Delete following folder C:\Users\%username%\AppData\Local\Microsoft\VisualStudio\xx.x\ComponentModelCache and file C:\Users\%username%\AppData\Roaming\Microsoft\VisualStudio\xx.x\ActivityLog.xml

Restart Visual Studio
