How do I install my account to windows, purchased from Google playstore

Hi,

It is not clear what you mean by “How do I install my account to windows”.
A subscription purchased via Google Play will not be visible in your Avast Account.
Your Google Play subscription can only be used on an Android device (not a Windows device).
Would you please clarify if this does not answer your question?
