Cannot Uninstall DisplayLink Core Software

[Scotlanta]

I am unable to upgrade to 5.2, as a result of being unable to install the old version, now that I have upgraded to Windows 7.

Why? Because I manually deleted a number of the files associated with the software. Why? Because I was foolish.

So anyway, I am now unable to uninstall using Add/Remove programs on control panel (It simply fails to uninstall) and I am unable to upgrade (because it fails when first trying to uninstall the old version).

I am unable to manually remove the remaining old files (some are system files, and they say it requires admin permission. Yet *I* am the admin and the only user on this system lol).

So ... what to do what to do. HELP! Save me from myself!
