I’ve had a few successes with AdA recently. It applied its own update and I’ve received a couple of notices for updates too. This morning I got such a message about Navisworks but when I attempted to install it it I was informed the digital signature couldn’t be verified.
There didn’t appear to be any way around this via AdA so I visited the Autodesk Portal for my account. I found the update at the top of the list so I downloaded and installed it successfully that way instead.
