How to fix “Internal Diagnostics Hub Exception” in VS 2015 Update 1?

Question

I\'ve just updated to Visual Studio 2015 Update 1, and I\'m getting the error whenever I start debugging:

Internal Diagnostics Hub Exception. See log

Answer 1

The file PerformanceDebuggerSwimLanesView.html was missing from c:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Platform\DiagnosticsHub\WebViews\. After I copied over the file from a coworker, the error was fixed ;)

I've put the file in a gist, in case you want it.
