The 'ProviderPackage' package did not load correctly

Question

I installed Visual Studio 2012 and at a later date Update 2. After installing Update 2, when I load any project, I get the following error:

Answer 1

For me the ActivityLog.xml stated

Access to the path 'C:\Users\Klas\Documents\Visual Studio
2015\ArchitectureExplorer' is denied.

When I examined this folder I realized that the entire folder structure here

C:\Users\Klas\Documents\Visual Studio 2015

had permission set so that my user had no write permissions. I added Full Control rights to my user for this folder and everything below.

After that, the message went away. Also, when I started Visual Studio it created lots of subfolders to this folder.
