TUFLOW (all versions, engines, etc) runs using a hardware lock, or dongle, which are from a provider called "Wibu". Its called the Wibu Codemeter Dongle.

To activate the licence on a specific computer with a specific Wibu dongle, a licence request needs to be created. This request is done by the user, with the dongle attached to the computer, using the steps shown below. This creates a file (the .WibuCmRaC file), which is then sent to From there, we update the licence file (to include a specific version, or trial, etc) and return it to you.

New User Steps:

  1. Email with your purchase request. We will post you a hardware lock (dongle).
  2. Install codemeter software.
  3. Create licence file using codemeter software (.WibuCmRaC file).
  4. Email file to We will update the file with licence information, activating the TUFLOW FV licence.
