The Tasks dialog that is docked on the left side of the application by default in Promis.e Standalone and Bentley Substation is missing or was accidentally turned off.
Close and reopen the software and the menus will typically reappear.
Select Tools > Tasks from the pull down menus along the top of the screen.
If there is a check box next to Tasks, then the Task Bar menus should be on.
