Logitech Software showing continuous errors in event viewer, broadcasted streaming video drops constantly

This problem has carried on for several months with no reasonable solution.

Here is the skinny:

ASUS QUAD CORE workhorse of a computer, plenty of RAM, Plenty of guts
Logitech QuickCam Pro for Notebooks
Justin.tv web based broadcasting software installed and delivered via an activeX popup.

We've gone through the normal paths of installing the Logitech Camera, downloaded the latest installer from Logitech, ran the installer, confirmed tha the quickcam works with Skype as well as various other applications.  We use this webcam to broadcast live streaming video to the web. (Did we mention the quality is superb?)

Now the problem:
We get a lot of glitches with this system.  First, the feed drops constantly.  Our internet is still up when this happens and other Internet Explorer windows stay up, but when our feed crashes, the IE window we were broadcasting in crashes.  No warning, no error messages, just BAM! Gone!

I check the event viewer and I get this error message CONSTANTLY and I mean CONSTANTLY... PAGE AFTER PAGE in the event viewer: SOURCE MSI INSTALLER
Detection of product '{945AC98B-3DC8-45BE-BAE0-22CEEE37A103}', feature 'QuickCam', component '{B52C7B4D-F46F-438C-ADF2-05A138C57757}' failed.  The resource 'HKEY_CURRENT_USER\Software\Logitech\InstallerKeys\QCDesktopShortcutKey' does not exist.

Here's the difficult part:  This doesn't drop like this on our other computer, which is running the same software, the same hardware and broadcasting through the same website...

And finally:  Yes, I've uninstalled the logitech software countless times.  Gone as far as removing all traces from the registry.  It seems to be isolated to this computer.

Any thoughts?
