Manual Uninstall Desktop Video

I am having the "Greyed out in preferences" Problem. I have a thunderbolt shuttle. The preferences were visible earlier today, but the express would not detect source. I then installed an earlier version and now I have no control in the pref pane. I tried to uninstall and reboot with multiple versions to no avail. Is there a way to manually uninstall? Maybe an old files is hanging things up...




Lion 10.8.2

Model Identifier: MacBookPro9,2
Processor Name: Intel Core i7
Processor Speed: 2.9 GHz
Number of Processors: 1
Total Number of Cores: 2
L2 Cache (per Core): 256 KB
L3 Cache: 4 MB
Memory: 8 GB

I'm also trying to figure out how to manually uninstall Desktop Video... Windows "Uninstall" causes a reboot, and installing an older version (10.1.1, even though I downloaded 10.1.2??) gives the error: "The installer has encountered an unexpected error installing this package. This m ay indicate a problem with this package. The error code is 2753"

Can't uninstall now.
Can't install.
