  • Hi,

    Yes, it is possible that you have an anti-virus application that prevents processes from writing to that key. You could try to temporarily turn off Windows Defender to have a test.

  • I just checked on my Win10-1607 laptop, and that regkey is secured, but Windows Defender can edit it.

    So I opened up Settings -> Update & Security -> Windows Defender
    Add an Exclusion
    + Exclude a Folder
    [Browse to the desired folder to add it as an exclusion]
    [Save that new exclusion]
    [open regedit and navigate to the regkey and can see the new exclusion is listed there]

    Maybe that will be enough to allow the software installer to proceed?


    Don [doesn't work for MSFT, and they're probably glad about that ;]

  • Hi Alvin Wang,

    I have the same issue here and this solution not working. Do you have another solution?

    I just change my wifi card from Qualcomm Atheros AR9485WB-EG Wireless Network Adapter to Intel Dual Band AC7620. When I try to install the Bluetooth Driver, it show the message below:

    Could not write value C:\Program Files(x86)\Intel\Bluetooth\  to key \SOFTWARE\Microsoft\Windows Defender\Exclusions\Paths

    Appreciate if you could provide the solution to this, thanks a lot.

  • I too am having the same problem. Trying to install the Intel wireless bluetooth software and get the same "Could not write value" and same file location. Excluding that path with Windows Defender didn't help. What to do now?
