Hello Dave and Welcome to Roon.

That is a bummer when out the blue Roon acts up like this. There could be multiple reasons for this happening.

Have you tried Restoring Windows 10 to a date previous of this happening?

–MD

Yes, well what was able to be rolled back. No change in behaviour. I do have a log file i can upload

Still no go with starting Roon on the PC - i do have a log file, how do i upload that to enable diagnosis of the problem?

Dave,

Have tried to “Run As Administrator” when you launch program.

Hi there, i missed this comment. Yes i did try that (just now) and still wont start.

I did install it on a separate laptop and that booted up just fine and connected to the NUC straight away, so the system is working fine, just not on this PC.

Let’s see if it is your PC or Roon.

A Roon install would be tied to the Profile.

Can you create another local account? After it is created, make sure that you change it to a Administrator. By default it will be setup as a Standard User.

Log into this account and Install Roon.

Try Googling this code , it could be hardware or HDD errors

Hey @Dave_Lawie,

Sorry for the delay in getting to your thread! If you could, please upload your zipped log file folder here and our team will take a closer look. :+1:

In the meantime, lets refresh your Roon database to see if that helps:

  • Create a Backup of your current database
  • Exit out of Roon
  • Navigate to your Roon Database Location
  • Find the folder that says “Roon”
  • Rename the “Roon” folder to “Roon_old”
  • Reinstall the Roon App from our Downloads Page to generate a new Roon folder
  • Verify if the issue persists on a fresh database before restoring the backup

I’ll be on standby for your reply. :+1:

I tried renaming the database, still no-go, i have uploaded the event log

Hey @Dave_Lawie,

A set of Roon logs would be helpful as well. Please use the directions found here and send over a set of logs to our File Uploader. Thanks!

Can you also verify that Roon.exe and RAATserver.exe are both exceptions in your firewall settings?

Raatserver.exe was not on the allowed list. I enabled it but no change. I have uploaded the Roon logs as per above. Regards

Dave

Thanks @Dave_Lawie,

While our team investigates this deeper, could you also test out hardwiring your PC directly to your router, bypassing any network gear, and let me know if the issue persists?

Thanks!

The PC is already connected to the router via Ethernet, as is the NUC .

Hey @Dave_Lawie,

Thanks for giving that a try! As a follow-up, it may be good to completely remove and uninstall Roon from the PC, and attempt a full fresh install to test for corruption in the install files.

This would involve heading into your library folder and removing any Roon file (just make sure you don’t have any backups on the PC you’re removing Roon from.) From there, do a fresh install and let me know if you run into the same issue.

Thanks!

After chatting with the team @Dave_Lawie, we believe the issue may be more related to a miscommunication in hardware data between your PC and Roon. The below article may help with additional next steps:

https://www.makeuseof.com/fix-the-software-exception-0xc0000409-error-in-windows/

I ran most of that. Now i receive a Fatal Error - This device is not compatible with Roon 2.0.

It sounds as though you have the Compatibility Mode for an earlier version of Windows turned on. You need to turn it off. See:

Right-click the Roon shortcut on your Windows Desktop and choose “Properties” to bring up the Properties window. Select the Compatibility tab and make sure that the “Run this program in compatibility mode” checkbox is NOT checked…

that would have turned on running some of those tests.

Back to square one. The roon log
