Can't reinstall - Comodo thinks there's an old version present

Just attempted to install v3.5 after un-installing the previous version (this was done by Comodo’s request to uninstall the old version). But the install stops almost immediately with an error messasge saying there’s already an older version installed. I checked with the ADD REMOVE control panel as well as Revo Uninstaller and I don’t see any Comodo installed. HELP!

Try using Comodo Registry Cleaner & Make sure nothing is found in C:\Program Files\Comodo (Or if the folder doesn’t exist that’s good).
