I've installed Visual Studio Professional RTM that was released yesterday 20th July.
I've removed Just Code and reinstalled enabling it for VS2013 and VS2015 from the Control Toolbox installer this evening.
The menu does not display where expected in VS2015. It does in VS2013.
"An error occurred loading this property page" message is displayed in Options->Just Code in VS2015.
This is all the information I have on this.
Any help getting things working much appreciated.
