When you have purchased a Sonargraph license, an activation code or a license file will be delivered to you.

There might be a program for free Sonargraph licenses which are time-limited and/or size-limited. Please register on our website and check the available programs.

In order to replace a valid license by a new one, choose "Help" → "Manage License..." from the user menu in the GUI-based product. Sonargraph licenses are bound to a named user. The usage by a different user is a violation of the license agreement.
