Upgrading Civil 3D

Sometimes upgrading doesn’t go as planned. I recently tried to use Civil 3D 2017 and I was unable to change the annotation scale. It froze and wouldn’t come back. The reason why is that it was waiting for an upgrade dialog box to say OK. Since it doesn’t show in the UI I was unable to press it. To get everything back to normal I ran the RecoverAll on the drawing. This processed both the drawing and all of the XREFs. All of the drawings are saved as well as having the dialog box pop up where I can press the OK button.
