Microsoft office 2010 still says its installed.

I had this problem before when I tried to upgrade from 2007 trial to full. Now, its happening with 2010. Basically, my system told me that I had to uninstall the beta. Easy enough. Then I try to install the new full version and it says to uninstall the program. I will post a screenshot later of the actual error. On campus ATM. ANYWAY, I tried to delete the registry keys and, basically, wipe it out of my system entirely. And that still didn’t work. I am totally lost and any help would be awesome. Thanks in advance.
Also, Windows 7 Ultimate x64. Let me know if I can provide any more info.
Answer #1
You could try using Revo Uninstaller to remove everything relating to MO 2010 Still on ur PC. Or use a Registry Cleaner, i prefer Tune Up Utilities.
Answer #2

That is the error and I don’t have anything else of Office 2010.
Also the only other things I have with 2010 in the title are not related to Office. Visual studio and the like.
