Uninstall Kerio Winroute Firewall

Hello, I have a serious issue here.  Something went wrong with my Kerio Winroute Firewall installation and now it won't unintsall.  I need to manually uninstall it and i have removed the folder in c:\program files\kerio but there must still be some registry entries involved.  when i open "Services" in ctrl panel i still see the entry "Kerio Winroute Firewall" listed.  what i was going to do is try and reinstall the program but it fails because it can't overwrite the existing Winroute Firewall service which is already listed!!

I need to find what is causing it to be listed in "Services" and manually remove the service somehow and really, any other registry entries pertaining to it!!

here is a list of items i found for kerio winroute firewall in the registry but i cannot delete them.
registry editor will not let me remove them:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\KWFLOWERDEVICEMP\0000
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\KWFLOWERDEVICEMP\0001
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\KWFLOWERDEVICEMP\0002
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\KWFLOWERDEVICEMP\0003
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\KWFLOWERDEVICEMP\0004

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Enum\Root\LEGACY_WINROUTE\0000

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\KWFLOWERDEVICEMP\0000
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\KWFLOWERDEVICEMP\0001
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\KWFLOWERDEVICEMP\0002
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\KWFLOWERDEVICEMP\0003
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\KWFLOWERDEVICEMP\0004

Is it one of these entries that is what is responsible for displaying the "Kerio Winroute Firewall" in the service listings?

please if you can, tell me how to properly remove these items!
thanks!
