New App Engine Project - SDK directory

Hello,

I am trying to create Google Cloud App Engine Project with PHP Storm, but not able to specify SDK directory. Always getting "Please specify valid SDK directory..."

I downloaded SDK Windows (x86_64) with Python bundled from here https://cloud.google.com/sdk/downloads . Exctracted to C:\GoogleCloudSDK.  I tried to navigate to C:\GoogleCloudSDK\bin folder that contains dev_appserver.py and gcloud - doesn't work.

After installation I tried new sub folders:C:\Program Files (x86)\Google\Cloud SDK

I think I tried all folders already.

What I am missing?
