Question QI-005 (continued)

Please note that the following instructions are for installation of a floating license on Windows computers only.

The installation instructions for various other license types and platforms may be found here.

System ID for Floating License

The system ID for the floating license is obtained by running the "EchoID" program.

  Start > Programs > ADINA System n.n > Floating License > Run EchoID

The Lock Code 1 ID is the system ID that you need to send to ADINA R & D (email: to obtain the license file.

Start Floating License Server

The floating license file must be named "lservrc" and be placed in the %ADINAHOME%\Sentinel directory. Typically, %ADINAHOME% is the directory "C:\Program Files\ADINA\ADINA System n.n".

To start the ADINA floating license server, run

  Start > Programs > ADINA System n.n > Floating License > License Server

Click the Add button [A] to start the license server. When successfully started, the following message is displayed.

If the license server if already running and you click Add, the following error message is displayed.

In Windows 7, when you click the Add or Remove button, you may get the following error:

In this case, click OK, close the previous window, and then, instead of running

  Start > Programs > ADINA System n.n > Floating License > License Server
by the usual left mouse click, right-click and choose 'Run as administrator'. This will allow you to Add and Remove normally.

Stop Floating License Server

If you need to stop the license server, click the Remove button [B]. When the license server is successfully stopped, the following message is displayed.

Restart Floating License Server

If you need to restart the license server, click on the Remove button and then the Add button.

License Checking Utility

You can use the "WlmAdmin.exe" utility program to check the status of the licenses on the license server. This program is in the %ADINAHOME%\Sentinel directory.

You can query a server [A] by specifying the server name or IP address via menu:

  Edit > Define Server List
If the license server has been started and has license features, the list of features will be shown below the server [B]. Clicking on a feature name displays the detailed information for the license feature [C].

Total users [D] indicates the maximum number sessions that can be run for a licensed program at any one time on all machines combined. However, for educational licenses, an unlimited number of sessions can be run at any one time, regardless of the number indicated here.

End date [E] indicates when the license expires.

If the specified license server has not been started, the following error message is displayed.

Common Problems

No license features listed in WlmAdmin for the license server
The most common reason is that the license file "lservrc" is not placed in the %ADINAHOME%\Sentinel directory or the license file name has an extension (e.g., .dat or .txt). You may not see the extension in Window Explorer because the extension may be hidden (by default).

One way you can verify the existence of "lservrc" in the %ADINAHOME%\Sentinel directory is to open a Command window and go to the directory [A] to list the file [B].

Firewall prevents access of license server from clients
The ADINA floating license is based on SentinelLM which uses UDP port 5093 to communicate. You need to allow this port through your firewall for the ADINA floating license to work.

SentinelLM server already running for other programs
SentinelLM allows only one server program to run on one machine. If there is already a SentinelLM server running for some other program(s), you need to combine the ADINA "lservrc" license file with the existing license file and restart the license server program.

If the current license server program is running SentinelLM 7.0 or later, ADINA programs will be able to get the license from the license server. If not, you need to stop the current license server program, put the combined license file to the %ADINAHOME%\Sentinel directory and start the ADINA license server program (see Start License Server above). The other programs should be able to obtain the licenses as usual. You can run WlmAdmin.exe to verify that all the license features are there.

Additional Information

Please refer to the README file in the %ADINAHOME%\Sentinel directory for more information.
