【error】license Manager Error -39

  • license Manager Error -39

User/host not on INCLUDE list for feature

  • Licensing error: -39,147


Where are the license files for MATLAB located?

In general, the default license file is license.dat for a full license and demo.lic for a trial.

Standalone Named User

Application Data folder on Windows or the user’s home directory for all other operating systems. For example, the file for R2008a is located:

  • C:\Documents and Settings\<username>\Application Data\MathWorks\MATLAB\R2008a_licenses (for Windows)
  • /home/<username>/.matlab/R2008a_licenses (for Unix/Linux/Mac)
  • /Users/<username>/.matlab/R2012b_licenses (Mountain Lion OS 10.8)

NOTE: Application Data may vary on Windows. To get to the actual Application Data folder, enter %APPDATA% into Windows explorer and click “Go” to get to that location.
Generally the license file located here will be named:
license_<hostname>_<license #>_<MATLAB version>.lic
ex: license_my-computer_123456_R2008a.lic

Designated Computer

$MATLAB\licenses for all platforms.

The license file naming convention will be the same: license_<hostname>_<license #>_<MATLAB version>.lic

Network Concurrent or Network Named User

The license.dat file on the server machine is located in:
$MATLABROOT/etc ($MATLAB\flexlm for releases prior to R2010b on Windows)

 On the Client computer, the license file location is $MATLAB\licenses for all platforms. The license file name will be network.lic in this case.

The license file will be called {demo|trial}_<trial #>_<MATLAB version>.lic and will be placed in the $MATLAB\licenses folder as well.

R2007b and below
For versions prior to R2008a, the license file is located in either:
$MATLAB\bin\win{32|64} (For Windows)
$MATLAB/etc (For all other operating systems)


Error -39 indicates that you are logged into your computer as a user who is not authorized to use your MATLAB license. This error is most often caused by an incorrect username on the INCLUDE line of your Options file (MLM.opt), located on the license server in the directory below:


$MATLAB\etc\win{32|64} ($MATLAB\flexlm for releases prior to 2010b)

$MATLAB/etc/glnx{86|a64} ($MATLAB/etc for releases prior to 2010b)
How do I RESERVE licenses for specific users?
