This post describes how to install 12d Model.

If you have just purchased 12d Model and you want to install the program, or you have 12d Model and you want to install it onto a new computer, you are in the right place.

Installing 12d Model has four steps

  1. Install dongle drivers
  2. Attach the dongle
  3. Install 12d Model
  4. Authorise 12d Model

These four steps are described in more detail below.

If you already have 12d Model installed on your computer, and you need to install a new authorisation file, please see instructions in this page.

If you have 12d Model 12 installed on your machine, and you want to upgrade to 12d Model 14 please see the instructions on this page

1.     Install Dongle Drivers

Dongle drivers must be installed BEFORE you attach the dongle to computer.

12d Model uses two types of dongle, ‘WIBU’ and ‘Codemeter’

Codemeter Dongles

If you have a miniUSB dongle, or a silver dongle then you have a ‘Codemeter’ dongle.
Codemeter dongle numbers start with ‘5c2d’
Select CodeMeter Drivers during the install.

WIBU Dongles

WIBU dongles are green, and the dongle numbers start with ‘572d’
Select Wibu Drivers during the install.

12d Solutions Installer

12d Solutions provides an installer that will install both WIBU and Codemeter dongle drivers.
Download the installer from this page , (open the page, select the ‘download‘ link under ‘New Wibu drivers and CodeMeter drivers (Combined 32bit & 64bit)‘)
This short video shows the process for installing dongle drivers using the 12d Solutions installer.

2.     Attach the Dongle

O.K. so this is a bit obvious.

The important thing to remember is to attach the dongle to the computer AFTER you have installed the dongle drivers

3.     Install 12d Model

12d Model can be downloaded from the 12d Solutions website, or from the 12d User Forum or from the links below.

The version on the User Forum is usually later (newer and better) than the version on the website.
You will need to log on to the forum to access the download.

The installer is a large download – about 1Gb.

Once the installer has been downloaded, simply double click on the file to install 12d Model


Note that if you already have 12d Model installed, you will be asked if you want to un-install the existing version.  The correct answer is ‘Yes’
You will then be warned:  ‘Proceeding with the uninstaller will delete all files from your installation directory’.  You should press ‘Yes’ to continue.
The installer writes files to the ‘Program Files’ area of your computer.  None of your projects or configuration are stored in this area, so your work will not be affected by the installation.

These links to download 12d Model have been copied from the 12d Solutions website.  Go for it!

4.     Install the Authorisation File

You will have been sent an authorisation file for 12d Model.

For 12d Model 12 the file is nodes.12d12n
For 12d Model 14 the file is nodes.12d14n

As you would expect the file is often referred to as the ‘nodes file’

The authorisation file for 12d Model is usually sent to you as an attachment to an email.

To use the authorisation file, simply double-click on it.
A panel will open as shown below.

Press ‘Install’ to authorise your copy of 12d Model.

The ‘Operation’ can be ‘Prepend’ or ‘Replace’.   Not NOT choose ‘Append’.

Some email systems will not allow you to run the attachment from the email.  In this case you will need to save the file to your desktop then double-click it.

Instructions for manual installation:

For version 12 of 12d Model:

  1. Save the ‘nodes.12d12n’ file to the folder: “C:\12d\12.00\”
  2. Rename the file to “nodes.4d”


For version 14 of 12d Model:

  1. Save the ‘nodes.12d14n’ file to the folder: “C:\12d\14.00\”
  2. Rename the file to “nodes.4d”

After completing these steps, you should be able to start 12d Model Software using the desktop icon.

If 12d Model does not start an “Authorization Error” panel will be displayed.

For information about the errors and how to solve these, please refer to Wiki page “Error starting 12d Model


Certifying Codemeter Dongles

Codemeter dongles have a security feature that requires them to be Certified over the internet every 60 days.
This will happen automatically if your computer is connected to the internet, and you will not even know that it has happened.
You can manually certify the dongle from inside 12d Model using Project=>Management=>Dongles=>Certify codemeter.

If you have difficulty Certifying the dongle, refer to this page.
