Licensing Issues: How to Resolve them

Cannot connect to license server system

Asreml is unable to connect to the license server system specified in the asreml.lic file (the Asreml license file).

ASReml License Error
Cannot connect to license server system.
The license server manager (lmgrd) has not been started yet,
the wrong port@host or license file is being used, or the
port or hostname in the license file has been changed

This could be due to:

  1. Firewall problems
  2. Misspelling of the server name
  3. Failure to resolve the IP address from the name
  4. The wrong port number used in the license file.

License Server May Already be Running

(For Flexnet Floating Licenses)
The error message – ‘License Server May Already Be Running!!’ indicates that the existing license server processes (VSN.EXE and lmgrd.exe) are still running using the old license file, or that the TCP sockets they require have not yet been closed (they may be in the TIME_WAIT state). This state usually lasts for a few minutes before the sockets are terminated. Make sure these are not active before trying to launch again.

Flexnet error -96,491 reports that the lmtools application is unable to contact the license server on port 6983/6984 on host DESKTOP-T360CBI. Create an empty text file on your system to act as a destination for the license server debug log. Enter the path to this file in the LMTOOL ‘Config Services’ dialog and try to start the server again.

Please send the content of your vsn.lic file and the debug log file content if this problem persists.

No license for product (-1)

To activate your license, use the asreml.license.activate() command.
You can find full instructions in the ASReml-R Installation Guide.

No such feature exists. Feature: ASReml

(For Flexnet Licenses)
1. This could indicate the FLEXnet utilities daemons have not been upgraded to the version that ASReml uses. Please update your lmgrd and restart your license server.

2. This error will also occur if you don’t have a license for the ASReml product in your license server file. Please send us:

  • the contents of your license server file (vsni.lic)
  • the name of the ASReml R package file that you installed.

Installing License Server on a Virtual Machine

You can use VSNi software within a virtual environment only if the VSNi License Server is installed on a PHYSICAL (i.e. NOT virtual) machine. The virtual machines will need to communicate with the physical server to obtain a licence.

Testing your installation
After you have setup the VSNi License Server you can test the installation using a utility application included with the installation.

On Windows this can be found here:  C:\VSNi_LicenseServer_Win_x64\lmutil.exe

On Linux or MacOS it would be ${HOME}/VSN_License_Server_v11.14.0.0/lmutil

Once the license server installation is complete the first tests must be on the license server itself.

Using a command or terminal session execute the following command:

C:\VSNi_LicenseServer_Win_x64\lmutil.exe stat -c \ProgramData\VSNi\asreml.lic -S VSN

This will provide a status report on all VSN features served by the Licence Server nominated in the asreml.lic file.

Here is the report generated by our own license server :

Cannot open shared object file: No such file or directory - Linux

When you run ‘RequestLicense’ the following message appears.

your_filepath/RequestLicense: error while loading shared libraries:
library_name: cannot open shared object file: No such file or directory

If you are installing from a tar archive you will need to manually install all dependent libraries. This can be done on Centos systems using ‘yum provides’ followed by ‘yum install’ for each dependency. For example:

yum provides libpng12
yum install -y libpng12-1.2.50-10.el7.x86_64


Download the rpm package. Install with the command:

yum install asreml-

You will need to successfully run the following system configuration commands using the ‘root’ user account. (These instructions assume your target system is based on a 64 Bit Intel CPU).

$ sudo apt-get install --no-install-recommends -y libxft2 libjpeg62 libxt6 libxmu6
$ curl -O http://security.ubuntu.com/ubuntu/pool/main/libx/libxp/libxp6_1.0.2-2_amd64.deb
$ sudo dpkg -i /libxp6_1.0.2-2_amd64.deb

Download and install the latest ASReml 4 release with the command sequence:

$ mkdir ~/asreml
$ cd ~/asreml
$ curl -O http://www.vsni.co.uk/downloads/software/asreml/release4/
$ tar xf asreml-
$ sudo ln ~/asreml/bin/asreml.sh /usr/bin/asreml

Now you can launch ASReml to begin the license registration process.

$ asreml
