Logitech iTouch error

[General Crespin]

I had some problems with the Kerio firewall and Logitech SetPoint, I think I may have blocked something I should have allowed. To fix it I uninstalled both, and then reinstalled SetPoint. Now when I try to reinstall iTouch I get the following error message:

Anyone have any ideas? I've tried cleaning the registry of all iTouch references, I tried uninstalling SetPoint and installing iTouch first, I tried installing for both mouse and keyboard when SetPoint gives you the option at install, but nothing is working. I've never seen anything like this before.

Thanks for any help- iTouch may be one more process in the background, but I love my Logitech Elite keyboard.

EDIT: When I've bashed it into so many noob's heads on other forums, you'd think I remember... but someone may now bash my head in. Using that oh-so-useful Search function, I found a link to the solution.
