The solution to this has been posted now over and over and over again in these forums. So you can search there,
OR you could have just Google'd your question, which would have brought you to any one of the threads which answer the question
You could also just have pinged Stardock support as I assume they have read these forums again for this answer as well.
But I will post the solution again for ya!
-------
Okay, I was able to get it to work thanks to a combination of what people have said above.
1) Uninstall OD+ 190.033 from within Impulse
2) Reboot
3a) You'll need to download and install SDC, Stardock Central from here http://sd.stardock.com/sdcentral_setup.exe
3b) Using SDC, install 190i[b].020 of ObjectDock Plus
4) Run OD+ from the Start menu etc (wouldn't run from SDC directly for me).
5) Be happy. 
I manually made sure "Enable MCP notification area support" and "Enable MCP SmartStartup" are CHECKED in the SDC/Tools/Settings/General tab, but I don't know if that is required. I did this in SDC before rebooting above, just fyi.
I now have Start Button and System Tray on Zooming docks support under Vista 64 Ultimate.
I hope this helps and again, thank you to Wally3k, et al, for their helpful comments.
