NTK Daemon ''Error Service' NTK Daemon Service' failed to start

Hey @Kornel and @Hardy Tilger

Maybe your antivirus or firewall got in the way?

What antivirus and firewall do each of you use?

If that's possible, try deactivating one or both, then retry the installer as noted by Jester above. Be sure to run the installer "as administrator" as it says in the instructions.

Just be sure to reactivate your security when done.

If you're still having trouble after doing the above, then do this:

Please open Windows 11 task manager, and go to the Processes tab. Click on "name" (so that the list sorts by name), then scroll down and see if NTKDaemonService appears in the list.

If yes, then right click on it (not the higher level "NTKDAEMON" with the old NI logo...no, you must right click on the lower level one named "NTKDaemonService") and select "Services". This will open Windows services. Sort by name and scroll down to find NTKDaemonService.

What does it say? Is it running? Failed to run? Please tell us the state reported by Windows 11 Services, and we'll come up with something else to try.

For example, mine says "Running", "Automatic (Delayed Start)", and "Local System".

I'm looking for something like "Disabled" or "Failed to Start", and maybe some clues as to why.

Power User Tip:

This is just general good advice. Whenever installing software, be alert for any popup messages from Windows. They most likely will appear in the lower right corner of your primary monitor, but if you're daydreaming or goofing around in your studio, you might miss them.

I just installed something today (not NI, but still), and I got a popup. I clicked on it, and it gave me a yes/no choice to give authority for something or other. Which I did, and then the install went fine.

I also have the same issue, also on Windows 11. I "fixed" the issue once with downgrading, but due to updates it broke again.
The NTKDaemon installs and starts just fine (I can see it in the services in Windows), I am not getting any dependencies errors , but whenever I try to start Native Access I get the error message "Unable to start the NTK Daemon. Please restart Native Access. If the issue persists, please contact support."

I did try reinstalling multiple versions of the NTK Daemon that I have at hand (1.17.2 and 1.16.0), but neither seem to work with Native Access.

And the NTK Daemon starts just fine. I can see it in the Windows Services list that it is started. Forcing it to end and restart also doesn't solve the issue.

I found a log for Native Access, and it says there that my Daemon uses an incompatible protocol version 2.1.0, expected version is 2.0.0.

I have attached the corresponding log file. Any ideas on how to fix this issue?

I'm also experiencing the same issue and it's quite frustrating.

Here are my system specs:

• Processor: AMD Ryzen 7 5700X 8-Core Processor 3.40 GHz
• Installed RAM: 32.0 GB
• Edition: Windows 10 Pro
• Version: 22H2
• OS Build: 19045.4842

Here's what I've tried during NTKDaemon installation:

1. Manually started NTKDaemonService
2. Checked and modified system service installation permissions

Other things I've tried:

1. Followed the instructions on Native Instruments' official support page
2. Clean boot
3. Registry cleaning
4. Ran System File Checker
5. Installed the latest Microsoft Visual C++
6. Ran Windows Update

Unfortunately, none of these methods have resolved the issue.

Are there any other solutions I could try? If not, I'm considering either repairing my OS or performing a clean install.
