Hello! I’m sorry to hear the Qobuz app isn’t starting on your Windows 10 machine. To help you better, could you share a bit more? For example, does the app show any sign of launching like a splash screen, or does it just stay completely unresponsive right after you click it? Also, have you recently updated the app or Windows itself?

Meanwhile, here’s a straightforward approach to try that often resolves app startup issues:

1. Restart Your Computer: It clears temporary glitches that might block the app from starting.

2. Run Qobuz as Administrator: Right-click the Qobuz shortcut and select "Run as administrator"—sometimes permissions prevent it from launching properly.

3. Check for Updates: Open the Microsoft Store or visit the Qobuz site to ensure your app is updated to the latest version.

4. Reinstall the App:
- Uninstall Qobuz from "Apps & Features".
- Restart your computer.
- Download and install the latest version from the official Qobuz website.

5. Clear App Cache/Data:
- Navigate to %LocalAppData%\Qobuz\ using File Explorer.
- Delete or rename this folder to force the app to create fresh cache files on next launch.

6. Check for Conflicting Software: Temporarily disable any antivirus or firewall to see if that’s blocking the app.

If none of these steps work, please let me know what you’ve tried already and if any error messages appear. That way, I can guide you to more detailed fixes or escalate if needed.

Are you satisfied with this approach so far, or is your situation a bit different?

I get a little rotating circle very briefly by the icon but that's it

Thanks for the detail about the brief rotating circle by the icon. That gives a helpful clue.

The behavior you describe — a quick spinning circle near the app icon but then no further launch or app window — often points to the Qobuz app struggling to fully start due to either a corrupted cache, an update issue, or interference with network or permissions.

Here’s a tailored set of next steps based on your Windows 10 setup and your symptom:

1. Clear App Cache Manually:
- Press Win + R to open the Run dialog.
- Type %LocalAppData%\Qobuz and hit Enter.
- Delete or rename the entire Qobuz folder here. This clears cache and config files that might block startup.

2. Check Internet Connectivity and Firewall:
- Make sure your internet is stable (try loading websites in your browser).
- Temporarily disable any firewall or antivirus software that might block the app’s connections, then try launching again.

3. Run Compatibility Troubleshooter:
- Right-click the Qobuz shortcut or executable.
- Select "Properties" → "Compatibility" tab → click "Run compatibility troubleshooter" and follow prompts.

4. Update or Roll Back Graphics Drivers:
- Outdated or problematic graphics drivers can sometimes prevent apps from rendering properly.
- Go to Device Manager → Display adapters → right-click your graphics device → "Update driver" to check for updates.
- If you recently updated drivers and issues started, consider rolling back.

5. Check for Windows Updates:
- Go to Settings → Update & Security → Windows Update → "Check for updates" and install any pending ones.

If none of this gets Qobuz to open past that spinning circle, we can try looking at logs or do a clean reinstall of the app with all support files removed. Please let me know what you’ve already tried, or if you want me to guide you step by step through any of the above!

Would you like to proceed with these steps?

Yes I'll work on it. It's been working for years ok but suddenly this problem. I'll just keep working on it per above instructions. On my iPad I got a notice of a Qobuz update but not on any other machines Mac or Windows.

Thanks for sharing that additional info about seeing an update notice on your iPad but not on your Mac or Windows devices. This actually aligns with what many users have noticed lately: Qobuz tends to release updates more frequently on iOS (like iPads and iPhones) than on Mac or Windows desktop apps. The desktop versions seem to receive updates less often and sometimes with a delay compared to mobile versions1.

This can explain why your iPad got the update prompt while your Windows machine hasn't yet—it’s more of a release schedule and platform difference than an error. The Windows app updates generally come through the official Qobuz website or Microsoft Store, so checking those occasionally is a good idea.

Since you mentioned the app has worked well for years before this sudden issue, the problem might be unrelated to updates and more about something local on your Windows computer (corrupted cache, permissions, network, or a recent Windows update causing a conflict). The steps we discussed earlier about clearing the cache folder, running as administrator, and checking firewall settings still stand as solid next moves.

If you’d like, I can also help you verify the current installed version of your Windows app and compare it to the latest available, and walk you through a clean reinstall if that sounds good.

Are you comfortable proceeding with those troubleshooting steps on your Windows device now? Or would you like help checking your app version first?
