After the update from 2…9.0.26 to 2.9.0.27 completed a pop-up window with “Adobe Distiller” in the title bar appeared with the message ‘Unable to create temporary folder when the file exists.’ (Unfortunately, I did not capture the screen so this is a paraphrase, but close.)
After dismissing the message Scrivener started with no apparent problems.
