ZBrush License Activation Error

How to fix it

Try these in order — the most common fix is first.

1. 1. Sign in and check the license

   Copy steps
   1. Open the Maxon App and sign in with the account that owns the license
   2. In ZBrush use the Check my License button to query the licensing server
   Did this fix it? Yes No

2. 2. Update ZBrush (trial license errors)

   Copy steps
   1. Update ZBrush through the Maxon App or the standalone installer
   2. If the error continues with the latest version, contact Maxon Support with license type, version and OS
   Did this fix it? Yes No

3. 3. Release an activation from an old machine

   Copy steps
   1. Open the Maxon App or my.maxon.net
   2. Release the activation on the computer you no longer use
   3. Activate on the new machine
   Did this fix it? Yes No

4. 4. Reset a corrupt legacy license

   Copy steps
   1. Close ZBrush
   2. Run the Pixologic License Manager from the ZBrush install folder
   3. Click Reset (per Maxon, other buttons do not clear the bad data)
   Did this fix it? Yes No

Symptoms

ZBrush says activation failed, a license error, or a corrupt license was detected; a trial or second machine will not activate.

Why it happens

• Outdated ZBrush build with a Maxon One trial license
• Corrupted legacy (Pixologic-era) license data
• Activation still held by an old computer
• Not signed in to the Maxon App
