Belkin Bluetooth Crap!

I couldnt upgrade my belkin bluetooth due to error "A later version Bluetooth Software is already installed on the this machine"
I tried removing the related registry, temp files, folders as instructed in the uninstall bluetooth at belkin website, then install again but it keep on telling me the above error message. Values that were deleted from registry that contain the following 1) bluetooth 2) belkin 3) widcomm 4) broadcom 5) btw
Any help in removing the "ghostly image" of the belkin.
