beta will not update

when will the beta version(which i have installed) allow me to update? 88)

Welcome to the forum.

All non-final versions do not have the ability to update. You must uninstall the existing and manually install a new beta when it’s out. If I misinterpreted your question and what you meant was the actual date, then nobody knows yet

It certainly is. One of the main reasons for release delays is thanks for Vista (:HUG):
