Resetting the Polar FlexNet (FLEXlm) Licence Path
Application Note AP610 

Resetting the FlexNet license path

It may be necessary on occasions (for example, when renewing FlexNet licenses) to reset the license settings in the registry to clear old or invalid license paths.

Navigate to where you have installed the Polar licence folder (the default path is C:\Program Files\Polar\Licences.)

Open lmtools and select the Utilities tab.

Click on list all Vendor paths. This will list the current license path for the Polar license file.

Lmtools Utilities

Type the name Polar in the Vendor Name field and browse to the new license file or type in the server path

For example, 27000@(your server name) or, if no port is allocated, @(your server name)

Override path

Select the Override Path button to update the license path and overwrite the old path (below)

New vendor path

For a floating license it may be necessary to perform a license reread (Start/Stop/Reread tab.)

Restart the software to check the new license settings.

Resetting the license path on 64-bit systems

At installation Microsoft Windows 64-bit versions create two program files folders, \Program Files and \Program Files(x86). 64-bit Windows redirects the \Program Files folder for all programs that are 32-bit during the installation to the \Program Files(x86) folder. 64-bit programs are installed into the \Program Files folder.

When installing on a 64-bit Windows operating system, therefore, Polar software (for example Si8000m, Si9000e, Speedstack, CGen) installs in the Program Files (x86)\Polar folder so the license will be located by default in Program Files (x86)\Polar\Licences.

Adding environment variables

If the above process is not successful it may be necessary to add an environment variable using the variable name: POLAR_LICENSE_FILE
The variable value will be either the server or license folder, C:\Program Files\Polar\Licences;27001@(server name)

To add environment variables:

Windows XP

Start|Control Panel|System|Advanced tab|Environment Variables|New... and add the Variable name and Variable value in their respective text boxes.

Windows 7

Start|Control Panel|System|Advanced System Settings|Environment Variables|New... and add the Variable name and Variable value in their respective text boxes.

Windows 8

Move the mouse to the top or bottom right corner of your display, from the sidebar choose Settings|Control Panel.

From Control Panel choose System|Advanced System Settings|Environment Variables|New... and add the Variable name and Variable value in their respective text boxes.

Please consult with your IT department before trying either of the above options.
