Automator actions

I can’t find any automator actions of DTO.
I tried to open workflow from the extras folder and I’m receiving the error message in automator - The action “Set current group” couldn’t be loaded because it cant be located. Try reinstalling the action"
How can I add actions DT actions?

Please ensure that DEVONthink Pro Office is installed in the folder /Applications and restart the computer. Does this fix the problem?
