Hi,

Normally, the incomplete or damaged configuration information should be restored if the device is uninstalled via the Device Manager and then installed again. 

If you haven't already tried that, then open the Device Manager, right-click on the "Realtek Bluetooth Adapter", select "Uninstall device" from the menu that opened, in the window that opens click "Uninstall" (verify "Attempt to remove the driver ..." is not selected!). Then click on the icon in the Device Manager's menu bar that appears to resemble a screen with a magnifier (says "Scan for hardware changes" when the mouse pointer is being hovered over it). That should reinstall the "Realtek Bluetooth Adapter" using the driver that still exists within the system. If the error has now disappeared, then you are lucky, if not, then report back here.

Hi, thank you for your reply. I tried this and sadly the problem persists.

The other thing you could try is to do the same again, but this time check the box for "Attempt to remove the driver ...". This will result in Windows either installing another still existing driver or asking you to provide a driver (so you point it to the location where you extracted the driver from TP-Link to).

If this also doesn't help, then there must be a bigger problem somewhere.

By the way, at the begin of your first post you mentioned you previously "deleted" the bluetooth drivers. Do you remember how exactly you deleted them?

Okay, I did uninstall the device and checked the box. Now when I scan for hardware changes, instead of showing "Realtek Bluetooth Adapter" it says "Generic Bluetooth Adapter", but it still has the yellow warning sign.

Regarding the PS3 bluetooth drivers removal, I did follow a guide from the creators of the bluetooth drivers for the PS3 controller to remove them. They recommended something called DriverStore Explorer. I also made sure to remove only the drivers that had them as the providers, at least that's what I want to believe. I might've deleted something else by accident.

If Windows reverted to "Generic Bluetooth Adapter" with a yellow mark, that means there is no other (previous) driver available that it could install on its own.

At this point you need to right-click the "Generic Bluetooth Adapter" and then choose "Update driver" and then "Browse my computer for drivers". (browse to the folder into which you extracted the driver zip file that you downloaded from TP-Link)

If this ends up again in the "Code 19" error, then it seems there is no easy solution to this problem.

This sadly did not work.

I appreciate your time.
