After installing NCrunch_VS2017_3.12.0.15.msi,
and ncrunch is non operational ...
I am getting the message below in the Risk/Progress bar
An exception was encountered while constructing the content of this frame. This information is also logged in "C:\Users\John Kennerley\AppData\Roaming\Microsoft\VisualStudio\15.0_f25537bd\ActivityLog.xml".

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
