Trying to create a hello world VSix project in VS2017 15.4.3. I added nothing to the base project generated by VS. When attempt to build I get the error:
Unable to locate the extensions directory. "ExternalSettingsManager::GetScopePaths failed to initialize PkgDefManager for C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\devenv.exe".
I've cleaned/rebuilt the project and cleared temp files. Running Win7 x64. Also running VS2015 and VS2013.
