Okay so for builds like HighFidelity-Beta-7262 and HighFidelity-Beta-7279 the install packages have stopped working completely. I’ve downloaded each several times. They ask for elevated privileges and then do nothing, no errors, no screens, nothing at all; whether the sandbox is already running or not. Next time system starts, there is 7150 running perfectly happily but wanting to be updated.
I’m on fully up to date Windows 10.
