Installed upgrade and now DevonThink Pro Office won't open

Just installed the latest upgrade but get an error message telling me I can’t open the application because it may be damaged or incomplete (see attached).

How do I fix this?

Something went wrong during download and installation of the update. The incomplete or damaged application file must be replaced.

  1. If the Sorter is running, click on the tab to open the Sorter panel. At the bottom of the panel, click on the cogwheel symbol and choose Quit.

  2. Move the DEVONthink application to the Trash.

  3. Go to the Download page and download and install a fresh copy of your application in the Applications folder.

  4. Launch the application and allow it to run the Install Add-Ons procedure.
