Illustrator and Dreamweaver both failed today, error 145. Windows 10. 3 other apps updated no problem. Unable to delete the directories listed under more info in spite of running Explorer under admin rights.

I shut down completely. Upon restart, Illustrator updated successfully. The failed Dreamweaver update had disappeared entirely. I had to search for the app to install it as it wasn't suggested. But it did install successfully.
