License Issues

I didn’t receive my license key

License keys are emailed to the address used at checkout within a few minutes of purchase.

  1. Check your spam or junk folder.
  2. Search for an email from noreply@huzen-software.nl or sales@huzen-software.nl.
  3. Use the Resend license page on this site and enter your purchase email address — your key will be resent immediately.
  4. If none of the above works, contact support.

Activation fails with “invalid key”

  • Make sure you are entering the key exactly as received — no extra spaces at the start or end.
  • Keys are case-sensitive.
  • Confirm the key is yours — Team licenses issue individual keys per seat, so make sure you’re using your own key, not a colleague’s.

Activation fails with “machine limit reached”

A Pro or Team license is active on one machine at a time. If you have already activated on another machine:

  1. Open HZN Queue Console on the other machine and open the About dialog, then click Deactivate license.
  2. Return to the new machine and activate again.

If you no longer have access to the old machine, contact support — we can reset the activation for you.

License suddenly deactivated

This can happen if:

  • You exceeded the machine switch limit (2 switches per day). Wait until the next day and try again.
  • The machine’s hardware identifier changed significantly (e.g. after replacing the logic board or a major OS reinstall). Contact support for a manual reset.
  • Your subscription lapsed. Check your subscription status at the email address used for purchase.

Trial expired but I haven’t purchased yet

After the 14-day trial ends, the app shows a license gate and requires a key to continue. To purchase, go to the pricing page and choose a plan. Activate the received key in the app via the About dialog.

My subscription renewed but the app says it’s expired

License validity is checked online at launch. If the app incorrectly reports an expired license:

  1. Make sure your machine has internet access.
  2. Quit and relaunch the app to force a fresh validation check.
  3. If the issue persists, contact support with your license key and we’ll investigate.

Custom / Team license questions

For Custom (company-wide) licenses or Team seat management, email sales directly — these licenses are managed manually and do not go through the self-serve flow.
