bttray.exe entry point not found error on Start Up

HP Recommended
Microsoft Windows 10 (64-bit)

This issue has been raised and solved before. However when I go to install the Bluetooth drivers on the link 

"Link to update the Bluetooth driver"      didn't work as I think they were for Windows 8.1  Error 9998 ?     ,   can you attach a link compatible with windows 10 Pro please   ..Thanks 


"The procedure entry point ?SetOnHSPCallStatusChangeCallback@CWBtAPI@@QEAA?AW4WBtRc@@P6AXPEAXJJJJPEB_W@Z0@Z could not be located in the dynamic link library C:\Program Files\WIDCOMM\Bluetooth Software\BTTray.exe"

@GPLatest To check the operating system on your computer, click Start, right-click My Computer (or Computer), and then click Properties.

Check the operating system requirement for the update. If the operating system on the computer matches the operating system required for the update, follow these steps to install the update again:

  1. Restart the computer.

  2. Click Start, All Programs, Accessories, System Tools, and then click Disk Cleanup.

  3. Select the hard drive with the operating system (usually C:), and then click OK.

    Wait for disk cleanup to calculate how much disk space it can save.

  4. Select Temporary Files, and then click OK. It might take a while for the Disk Cleanup utility to remove the files.

    Figure : Disk Cleanup

    Disk Cleanup window
  5. Try to install the update again.
