Set Up a License Server on a Mac

As the account manager, how can I set up a server on a Mac for sharing SnapGene licenses among several computers?

Go to the Login Page

For this procedure, you must be the account manager for the SnapGene licenses in order to download the install files for the FlexNet Server.

Go to, and click on the Manage My Account link in the upper right corner.


Enter the email address and password for the account manager.

The original password was sent in an email immediately after purchase. If you have lost the password, click Lost Password to obtain a new password by email.

Download the Flexnet Install Files

The SnapGene team will provide a server installation file. Download the file FLEXnet_GSL_mac.dmg from your account page at and save it.

To share SnapGene licenses across several computers, first install the FLEXnet License Server on a network computer that will always be available.

Mount the Server Folder

To mount the server folder, double-click on FLEXnet_GSL_mac.dmg.

Install the Server Folder

To install the server folder, drag the mounted folder to a location on your hard drive, then double-click to open the folder.

Start the Server

Double-click the startServer file in the FLEXnet_GSL_mac folder.

Access the Server

To access the server, open a browser window, then type localhost:8090.

Sign In to the Server

Click the Administration link at the top right of the window.

To sign in, type the default User Name: admin and Password: admin, then click Submit.

Change the Password

To change the password, type the old and new passwords, then click Save.

Import the SnapGene Vendor Daemon License

To import the SnapGene Vendor Daemon license, click the Vendor Daemon Configuration button.

Then click the Import License button.

Click Choose File, browse to the .lic file sent to you by the SnapGene team, then click Import License.

Note: If you received a new license file (e.g., for additional licenses), instead check the box for Overwrite License File on License Server, then click Import License.

Configuration of the license server is complete. Click OK.

Eject the Drive

The virtual drive is no longer needed. To eject the virtual drive, right click on the FLEXnet GSL drive.

Review Shared License Usage

To review the current SnapGene license usage, click the Dashboard link, then click Concurrent. The number of licenses in use (and available) will be shown in the In Use column.  

Open Required Ports

If the computer running the license server restricts access to ports, then ports 27000 - 27009 need to be made accessible to client computers attempting to contact the server. The communication protocol is tcp.

Restart the Server When Necessary

For the licenses to be accessible, the administrator computer running this server must remain on. If the administrator computer is turned off and then back on, the server must be restarted. For this purpose, open the FLEXnet_GSL_mac folder and double-click the startServer file.
