Hi Bonnie,

Thank you for posting in Microsoft Community and being a part of Windows 10.

I understand your concern about connect the Bluetooth device on your device. We will help you with this issue.

Do let us know the following to assist you better with this issue:

  1. When exactly you get the above error message?
  2. What exactly happens when you try to connect the Bluetooth device?
  3. Were you able to detect the Bluetooth device in Device Manager?

This issue might have occurred if:

  • There is a previous installation of the same application on the machine and you try to install a newer version.
  • There are registry corruptions related to the application during upgrade.

Try the below troubleshooting steps and check if it helps.

Step 1: I suggest you to run SFC scan, System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files. If a Windows Resource Protection (WRP) file is missing or is corrupted, Windows may not behave as expected.


Step 2: I suggest you to run Microsoft Safety Scanner which help to remove viruses, spyware, and other malicious software.

Note: Data or files which are infected by malware might be beyond cleaning and have to be deleted entirely to maintain the integrity of your system, which means there might be a potential for data loss.

Step 3: If your Bluetooth device cannot be enabled or is missing from Settings, it is possible that your drivers are misconfigured.

I suggest you to refer to the below post replied by Rajith R on August 29, 2015 and check if it helps to resolve the issue.
