Goole_Dialogflow example, google-oauthlib-tool OSerror windows error 1

[Multimediabox]

I am trying to get the google_dialogflow example running, all seems to be working up until the authentication tool.
When i run the command as specified in the documentation i have th eproblem the consule doesn't let me enter the authentication code. If i remove -- headless it opens my browser, all works fine until i return to the consule i get the OSerror windows error 1

I am runnning the old envioremnt MSYS32 under Windows 10, the new enviorement doesnt support thye example today as i understand.
Command:
google-oauthlib-tool --scope https://www.googleapis.com/auth/cloud-platform \ --save --headless --client-secrets ~/esp/esp-va-sdk/examples/google_dialogflow/my client_secret json

The output:
# google-oauthlib-tool --scope https://www.googleapis.com/auth/cloud-platform --save --client-secrets ~/esp/esp-va-sdk/examples/google_dialogflow/My client_secret_json
