Installing Bluetooth driver

Latitude D620 w/ XP PRO, have all original Dell disc, but a never used Bluetooth. There is no driver and afraid to connect to the internet to go to Dell. Forced to retire, so I have PDF file to get from “Books” on an IPhone. Yep, but I don’t even have an account for the phone so using the WiFi side for everything. Sounds sad now that I write this, but at 62, my wife had foot bone spur, then new shoulder, lost weight and they where looking for cancer and found aneurism on aorta. I had L3 epidural, MRI, faced with lumbar fusion #4, as soon as elbow heels from ulnar nerve / carpal tunnel on good arm. So machines are failing, stacking up like cordwood, while tired body parts pain & back burning. Who win’s. Dr. or computer repair shop?

PS I have owned since new but had to reboot OS after hack. Help?
