Why am I getting a license error in ZBrush when using my Maxon One trial license?

This most commonly occurs when using anything other than the latest available version of ZBrush, in which case updating into the latest ZBrush version resolves the problem.

You can update into the latest version of ZBrush using the Maxon App or downloading the standalone installer.

If you are using the latest version and still having issues with your trial license, contact support.
