The FLEXlm License Management System protects TASKING products released before 2014. All TASKING toolsets are subject to the terms and conditions of the End-User License Agreement.

Supported License Types

The specific license type for your toolset will determine its allowed usage and transferability. UNIX products will only have a floating license type.

Node-Locked License
Node licenses locks your software to the computer it was installed on.

Floating License
Floating licenses are located on a license server and can be used by multiple users on a network.

How to Obtain a License

A license key is required to install and validate all TASKING products.
If you have not received a key follow the steps below to obtain one.


  1. Run the License Administrator during installation and follow the steps to request a license key from TASKING via email.
  2. Email the license request file to your local TASKING sales representative.
  3. Your license key will then be sent to you via email.


  1. Find Your Host ID and Host Name of the computer where you want to use the license manager.
  2. When you order a TASKING product provide your Host ID, Host Name, and a number of users to your sales representative.
  3. Your License key will then be sent to you via email.

How to Install a License

Installing Node-Locked Licenses

  1. Install your TASKING software product.
  2. Create a license file by importing a license key or creating one manually.

    • Importing License Key: During your software installation run the License Administrator (licadmin.exe) file. Follow the steps to Import a license key received from TASKING by Email.


    • Creating license key manually: Create a file called license.dat in the c:\flexlm directory using an ASCII editor and insert the license key information in the file

  3. Your TASKING software and license file are now properly installed.

Installing Floating Licenses

  1. Install your TASKING software product on each computer.
  2. Create a local license file or point to a license file on a server on each computer.
  3. (Skip this step if you’ve already installed FLEXlm v8.4 or higher) Install the Flexible License Manager (FLEXlm) on the license server where you want to use the license manager.
  4. Confirm that the directory of your FLEXlm product contains a copy of the TASKING executable (Tasking.exe or Tasking).
  5. On the license server add the license key to your licensing file.
  6. Run the license manager reread file (lmreread) to reread the modified license file.

Add a License Key to a Local License File

Windows: Follow the same steps for importing a license key or creating a license file manually.

Unix: Insert the license key manually in the license file. Default location of license.dat file is in directory /user/local/flexlm/licenses.

Point to a License File on the Server

Windows: Run the License Administrator and follow the steps to Point to a FLEXlm license Server to get your license.

Unix: Set the environment variable LM_LICENSE_FILE to “port@host” where port and host come from the SERVER line in the license file.

Modifying License File Location

The default location for the license file on Window/UNIX is:

Windows: c:\flexlm\license.dat
Unix: /usr/local/flexlm/licenses/license.dat

If you want to use another name or directory for the license file each user must define the environment variable LM_LICENSE_FILE.

Specifying Multiple License Files

If you have more than one product using the FLEXlm license manager you can specify multiple license files to the LM_LICENSE_FILE environment variable by separating each pathname (lfpath) with a semicolon ';' (on Windows), or colon ':' (on UNIX) like the examples below:

Windows: set LM_LICENSE_FILE=c:\flexlm\license.dat;c:\license.txt
Unix: setenv LM_LICENSE_FILE /usr/local/flexlm/licenses/license.dat:/myprod/license.txt

If the license file is not available on these hosts, you must set LM_LICENSE_FILE to port@host where the host is the hostname of the system which runs the FLEXlm license manager and port is the TCP/IP port number on which the license manager listens.

To obtain the port number, look in the license file at the host for a line starting with "SERVER". The fourth field on this line specifies the TCP/IP port number on which the license server listens. For example:
setenv LM_LICENSE_FILE 7594@elliot

How to Determine the Host ID and Host Name

Host ID

The Host ID depends on the platform of the machine. Please use one of the methods listed below to determine the host ID.

Platform Retrieval Tool Example

landscan (use station address without leading ‘0x’)



/sbin/ifconfig eth0 (Use HWaddr without the colons)






licadmin (License Administrator)


Note: When using a laptop connected to a network disconnect the network first before starting the License Administrator. Otherwise your license will not work when disconnected from the network.

Host Name

To retrieve the Host Name of a machine, use one of the following methods.

Platform Method


Windows NT

licadmin (License Administrator) or:

- Open the Control Panel then select Network.

- On the Identification tab look for Computer Name.

Windows 2000/XP

licadmin (License Administrator) or:

- Open the Control Panel then select System.

- On the Network Identification tab (Windows 2000) or Computer Name tab (Windows XP) look for Full Computer Name

Windows 8

Open the Control Panel, select System and Security and then choose System.

Note: The hostname is only necessary for floating licenses.
