How to properly uninstall Intel PROSet/Wireless Software for Bluetooth

Today I installed by mistake the Intel® PROSet/Wireless Software for Bluetooth® on my laptop.

When I tried to uninstall it,  I received an error and could not remove the software.

So, a battle begins: Me vs Uninstaller… The uninstaller was clearly winning, but not for long.

I did some searches at Google and saw several people with the same problem, however, no acceptable solution.

So, based on my past knowledge, I had an idea and I pushed it forward.


First of all, I downloaded a tool called ORCA (this tool allows you to edit MSI files).


As you can see, there are two rows in the picture above with the following actions: UnregisterOPP and RollbackUnregisterOPP.

You may ask why these lines are relevant. Well, if you look in Event Viewer, you will see a application error raised by the uninstaller.

Product: Intel(R) PROSet/Wireless Software for Bluetooth(R) Technology — Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Action: UnregisterOPP, location: C:\Program Files (x86)\Intel\Bluetooth\, command: “C:\Windows\System32\fsquirt.exe” -Register

The uninstaller tries to execute that command and fails because the file doesn’t exist.


From what I could understand, this file fsquirt.exe was used in Windows XP to provide Bluetooth support and was removed in newer versions of Windows.

For this reason, I decided to create an executable application that returns code 0 (success) in his main function.


After building it, I just put the file fsquirt.exe in the folder C:\Windows\System32\ and tried to run the uninstaller again.

This time I saw a message saying the uninstall was completed successfully.

So all files, registry changes and services was properly removed, leaving no trace behind.


If you want, you can use the same file that I made for this task.

You can delete fsquirt.exe from your System32 folder after the uninstall is complete.



PS: It’s a zip file, you need to extract it on system32.

    Success! Your fquirt.exe solved my problem, even though it wasn’t the fquirt.exe that was giving me issues. For me, Intel was complaining about “BTHSSecurityMgr.exe” and some other exe. I simply made two copies of “fsquirt.exe” in “C:\program files\Intel\BluetoothHS\” then renamed them appropriately.

    I almost can’t believe it! Thanks a million.

    I have the same problem but it’s “libRun” in C:\Program Files (x86)\Intel\Bluetooth

    I try to replace it with your “fsquirt” rename in libRun, but after that, i always had the same problem.

    Please help, I cant even find the folder C:\program files\Intel\BluetoothHS\ and BTHSSecurityMgr.exe and yet when I try to install new driver they still force me to uninstall it

      Sorry mate for the late reply.

      Did you tried the folder?
      C:\program files (x86)\Intel\Bluetooth

      Maybe you can send me the link of the driver you are trying to install, I can take a look along with the error message.

      Good luck 😉

    If I had money, I would give it to you right now. Your solution worked awesomely tidy.
    In my case, there was 2 different exe files that the setup looked for, but I replaced them with the one you provided and that was it

      Good to know it still works.
      Remember me if you get some, I’ll be here 😛
