I am running a sample file for a Python Standalone Application, 'PythonStandalone_01_new_file_and_quickfocus.py' and the developer environment (Visual Studio Code) flags up 2 problems:

Unable to import 'ZOSAPI-NetHelper'

Unable to import 'ZOSAPI'

The relevant lines of code in the sample file are:

        aKey = winreg.OpenKey(winreg.ConnectRegistry(None, winreg.HKEY_CURRENT_USER), r'Software\Zemax', 0, winreg.KEY_READ)
        zemaxData = winreg.QueryValueEx(aKey, 'ZemaxRoot')
        NetHelper = os.path.join(os.sep, zemaxData[0], r'ZOS-API\Libraries\ZOSAPI_NetHelper.dll')
        winreg.CloseKey(aKey)
        clr.AddReference(NetHelper)
        import ZOSAPI_NetHelper

        import ZOSAPI

I can see that the dll files are present at the filepath location. 

The code does run and generates a zemax file. Do I need to worry about these problems?
