    My surface updated itself to Windows 10 1607 (Anniversary Update).

    After that, Unity is failing to run - "Machine identification is invalid for current license". it gives me a handy button to reactivate, however it's disabled.

    Anyone else see this after updating to 1607?

    Edit: Went into the Unity Store to manage my license (as the help suggested), and removed all activations. Now attempting to activate gives the following error (sic):

    "License server return unknown error. Please contact support@unity3d.com for more information"

    I was able to get running again after removing activations (above) and reinstalling and reactivating.
