Yeah don't install the cd that comes with bluetooth headset. In case you did, just run setup from the CD again and click through till you get the remove option. Once you remove the program, your bluetooth will work fine. The problem is that the CD is for a hardware that is not on your system. To fix the bluetooth headset problem, just take your headset and hold the middle button (With the phone icon) for a really long time. The light will blink red and blue alternatively for a couple of times. Remember you have to hold it for a long time and do not release once you see a light.  After this your computer or phone will be able to detect the handset. Goodluck.
