Preparation for Installation of a Floating License Server

The only requirement for setting up a C-Cubed add-in floating license server is to ensure that the TCP port used by the license server is open for incoming traffic. The port number is included in the email you received with your floating license key.

Contact your system administrator for help in opening the port in your firewall. You can also refer to one of the following articles for the steps required to open the port on the computer hosting the C-Cubed license server. Note that floating license servers for different C-Cubed add-ins operate through a different ports. You will need to open a specific port for each license server hosted on the server.

Installing a Floating License Server

If you plan to use floating licenses for some or all of your computers you must download and install the floating license server for the add-in. Each C-Cubed add-in that supports floating licenses uses a separate floating license server. Using floating licenses may reduce the number of licenses required for your work group. You can combine floating and fixed licenses for any C-Cubed add-in that supports them.

For example, you could purchase ten (10) floating licenses for your engineering workgroup, and a three (3) license pack of fixed licenses to be installed on laptop machines that may not always be connected to your network.


The iPropWiz 7 license server is intended to work on a local network for a local set of users. Although we do not officially support serving licenses across WANs or domains, many customers have had success in doing so. We do not support converting floating licenses to fixed licenses (unless you also have a local license key), nor can we guarantee solutions for complex networking environments. The iPropWiz 7 floating license server does not use the same technology as floating licenses for Autodesk products, or Autodesk's new named-user licensing scheme.

For computers that are using a floating license, the add-in obtains a license from the floating license server when the add-in is first used. The license is released when Autodesk Inventor is closed, making it available to another user. If all available licenses have been assigned from the server, no other users will be able to obtain a license until one or more licenses have been released by current users.

To increase the number of floating licenses the server can dispense, please purchase addtional floating licenses.

Important: To activate the floating license server license, the server must be able to access the authentication service on our website. You may need to configure your security settings to enable this. This also applies when you renew the license subscription or update the number of floating licenses.

You must have Administrator permissions on the computer where you install the floating license server. See below for installing the license server as an administrator.

Floating license server applications do not include an evaluation period. You must activate the floating license server license before you can obtain licenses from it.

  1. Download the Floating License Server zip file for the specific add-in.

  2. Unzip the files to a folder on the computer that will act as the floating license server.

  3. Open a Command Prompt window with the "Run as Administrator" option.

  4. In the Command Propmpt window, enter the full path to the _Install_[add-in name]_Service.bat file.

  5. For example if the folder containing the .bat file is D:\MyLicServer\[add-in name]LicenseService\, enter D:\MyLicServer\[add-in name]LicenseService\_Install_[add-in name]_Service.bat

    The installation progress of the license service is shown in the command prompt window. Confirm that the license server was successfully installed.
    The Install License dialog is displayed once the Windows service is successfully installed.

  6. Copy and paste the floating license key you received in an email after purchasing the add-in. Click Activate.

  7. If successful, the License Status will change to License Installed.

    Note: If the license is a subscription, the end date for your subscription is also displayed. You will receive renewal notifications near the end of your subscription term.

    If there is an issue authenticating your license, an explanation message is displayed.

  8. Click Done to complete the activation.


    If the license activation was successful, a confirmation message indicates the number of floating licenses available from the server.

    If the license activation is not successful, a confirmation message is shown indicating zero (0) licenses were installed. If you see this message, run the _Uninstall_[add-in name]_Service.bat file from the command window to ensure the floating license server is uninstalled.

    On activation, a license file is saved to the same folder on the server. Two log files that document the installation are also saved here. Do not move the license file (.lic) from this folder.

    Optonally, you can save a copy of the license file to another location. In the activation dialog box, click Save License. Save the backup with a descriptive name identifying the computer where it is used. You can also manually copy the license file described above to a backup location.

Manual Activation of a Floating License Server License

If the C-Cubed license activation server cannot be reached when you try to activate your license, an Authentication Error message is displayed. Typically this is caused by a firewall or proxy server on your system preventing access to the authentication service.

  1. Click Yes to save the license file for manual activation. Save the file using a descriptive name.

  2. In the Install License dialog box, click Done. A message is displayed indicating zero (0) floating licenses are installed.

  3. In the folder, double-click the _Uninstall_[add-in name]_Service.bat file. Wait for the command window to close.

  4. Email the saved license file to

  5.   We will activate the license and return the file to you.

  6. When you receive the activated license, follow the intallation steps outlined above.

  7. When the Install License dialog box is displayed, click Load License

  8. Browse to and open the activated license file. Click Done.
