ExactScan does not exist any more

After upgrading to 2.4 DevonThink Office Pro the menu entry to import document from exact scan is not available any more. This feature is very important to me, because it was the only way to import documents using my Scanner device.

Is there anyhting which I have to install manually to get this possibility again?

In 2.4 the scanner import method was rewritten (see Help > Release Notes).

Use File > Import > From Scanner or Camera …
