I think something went wrong with your VS installation information in the window registry. The easiest attempt is to try to repair your install, such that the registry information gets up to date.
I’m no expert but I’m studying the code and saw the VSAccessorModule which has the CanRunVisualStudio() method. This method uses the windows registry to determine the path. It searches for “InstallDir” in HKEY_LOCAL_MACHINE for a VS Version dependent RegistryKeyName. I assume this key is something like “Visual Studio 2013”. If my repairing your install does not work you can search your registry with “regedit” by hand for the “InstallDir” information of VS to ensure that it can be found.
