Web Performance and Load Test - the Web Test Recorder plugin loads but controls are grayed out in Windows 10 with IE 11

I had an issue with IE 11 where the Web Test Recorder was loading but all controls were grayed out.

I verified the “Web Test Recorder 14.0” and “Microsoft Web Test Recorder 14.0 Helper” add-ons were enabled in IE.

Then reset and restarted IE under (Tools> Internet Options> Advanced>Reset).  After that all IE add-ons were then disabled.  I re-enabled the Web Test Recorder add-ons when prompted. 

That resolved the issue with the controls being grayed out, but then I was getting a missing DLL exception clicking Pause or Stop during the recording: "System.DllNotFoundException: Unable to load DLL 'Microsoft.VisualStudio.QualityTools.RecorderBarBHO100.x64.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)"

This site said to copy the DLL to the IE folder to resolve the missing DLL exception.

Copy Microsoft.VisualStudio.QualityTools.RecorderBarBHO100.dll (For older versions RecorderBarBHO90.dll  etc)  located under C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\PrivateAssemblies

To – C:\Program Files\Internet Explorer and for 64bit machines also Copy To – C:\Program Files (x86)\Internet Explorer

I copied the DLL to the IE folders and the issue is now resolved.
