Academic License not working

[eng.omar...@gmail.com]

I received a free academic license from Mosek because I am a graduate student.
When it was expired, I got another new one and replaced the old with the new one. However, MATLAB still says that Mosek license is expired.
My MATLAB version is r2012b
My Mosek version is 7

Thanks in advance

[Erling D. Andersen]

It might be that you have the OS variable

   MOSEKLM_LICENSE_FILE

defined and that is pointing to an old license. If that is the case remove then remove the setting. 

If that does not help, then please post the error messages in your reply.

I have the same issue. However, I'm not sure how to remove this OS variable.

I call mosek through yalmip.

[Erling D. Andersen]

A google search will bring up something like

   http://www.7tutorials.com/how-edit-or-delete-environment-variables-windows-7-windows-8

[S_Ade]

Oh thanks.

 However,  I do not have any environment variable by that name (MOSEKLM_LICENSE_FILE)  so the problem persists. 

I'm working a Windows 8.1 platform, Mosek version 7.

Thanks a lot.

[Erling D. Andersen]

Inside MATLAB run the command

      mosekdiag

and paste the output into you reply.

[S_Ade]

I get this error message from running mosekdiag, even with the new license file in place.

mosekopt: C:\Program Files\Mosek\7\toolbox\r2009b\mosekopt.mexw64

Error using mosekdiag (line 57)

mosekopt returned an error: 1008. [MSK_RES_ERR_MISSING_LICENSE_FILE]

[Erling D. Andersen]

MOSEK cannot locate the license file. So you cannot have done what is said in Section 2.1 at

   http://docs.mosek.com/7.0/toolsinstall/Obtaining_and_installing_a_license.html#section-node-_Obtaining%20and%20installing%20a%20license_Step%201:%20Installing%20the%20license%20file

Typically the license file is at

   c:\users\<userid>\mosek\mosek.lic

You cannot have that file.

[S_Ade]

It's probably an OS quirk. I re-installed Mosek, so it's working fine now.

Thanks.

[Erling D. Andersen]

Good to hear. Have fun with MOSEK.

Sir, 

   I am using MATLAB version R2013b, but in add path, as there is no option for R2013b, so I have selected R2013a. Now after typing mosekdiag in matlab: I am getting the error  mosekopt returned an error: 1008. [MSK_RES_ERR_MISSING_LICENSE_FILE]

. Plz help me

[ramakant singh]

mosekdiag

Matlab version: 8.2.0.701 (R2013b)

Architecture  : GLNXA64

Warning: The mosek optimizer could not be invoked from the command line. Most likely the path has not

been configured correctly. The mosek optimizer can still be invoked from the MATLAB environment.

mosekopt: /home/ramakant/mosek/7/toolbox/r2013a/mosekopt.mexa64

Error using mosekdiag (line 57)

mosekopt returned an error: 1008. [MSK_RES_ERR_MISSING_LICENSE_FILE]

 

[Joachim Dahl]

This means just what the error message says: MOSEK cannot be used from the command-line since the mosek executable is not in the search path,  but can still use the MOSEK toolbox from Matlab.

The installation instructions for the MATLAB toolbox can be found here:

http://docs.mosek.com/7.1/toolbox/Installation.html

About 10 lines down installation instructions explains how to setup the Matlab path for the different versions.

In mosek/7/toolbox directory, only R2009b, R2012a , R2012b, r2013a, r2013aom are present. But, I am using matlab version r2013b. As it is not there, I have selected R2013a. Now in mosekdiag command, I am getting error 1008. [MSK_RES_ERR_MISSING_LICENSE_FILE]

[Joachim Dahl]

From said installation instructions:

1. % For versions R2013a or newer  
2. addpath '/home/user/mosek/7/toolbox/r2013a'  

And to clarify possible confusions:  the MOSEK toolbox seems to work just fine. You are receiving a diagnostic warning that MOSEK cannot be run from the command line, most likely because the mosek binary is not in the search path of your terminal or shell,  but it doesn't matter as long as you use MOSEK from within MATLAB.

Are you experiencing problems running any of the Matlab examples in the documentation?

[ramakant singh]

That is fine. I noticed that thing that we can use R2013a for higher versions also. But, why I am getting the error:

> In mosekdiag at 23 

mosekopt: /home/ramakant/mosek/7/toolbox/r2013a/mosekopt.mexa64

Error using mosekdiag (line 57)

mosekopt returned an error: 1008. [MSK_RES_ERR_MISSING_LICENSE_FILE]

[Andrea Cassioli]

Hi,

the error message has nothing to do with the matlab toolbox, but with the license.

You should store the license file according to point 2.1 in 

http://docs.mosek.com/7.1/toolsinstall/Obtaining_and_installing_a_license.html#section-node-_Obtaining%20and%20installing%20a%20license_Step%201:%20Installing%20the%20license%20file

You do not need a token server.

If you plan to store the license file in a different folder you must set the env variable as suggested here

http://docs.mosek.com/7.1/toolsinstall/License_checkout.html#section-node-_License%20checkout_Using%20the%20OS%20variable%20MOSEKLM_LICENSE_FILE

Summarizing: the license file is not in a folder the solver can locate.

[ramakant singh]

Hii Andrea,

               I am using Ubuntu 13.04 and I have saved mosek.lic in home/ramakant/mosek  directory as specified in the link you mentioned. But I am getting the error. What could be other reasons ??

[Erling D. Andersen]

Please post whatever error messages you get. Thanks.

[p9g...@gmail.com]

Hello,

I have the same error....

Please notice that

- the file mosek.lic is located in the folder /home/user/mosek
- the downloaded mosek distribution has been unzipped and placed in /home/user/mosek/7
- the folder /home/user/mosek/7/toolbox/ has been added to the matlab path
- the env. variable $MOSEKLM_LICENSE_FILE is empty

this is the error I get in Matlab

[Erling Andersen]

Inside MATLAB try

!mosek -L  /home/user/mosek/mosek.lic

What is the output?

Are you saying

   MOSEKLM_LICENSE_FILE

is empty. That will cause problems. It must not be defined at all. 

So have have not setup the PATH variable. That is ok for MATLAB use but instead of

    mosek -L  /home/user/mosek/mosek.lic

you should do

!/home/user/mosek/7/tools/platform/linux64x86/mosek -L  /home/user/mosek/mosek.lic  /home/user/mosek/7/tools/examples/25fv47.mps

Also what happens if you do

!/home/user/mosek/7/tools/platform/linux64x86/mosek -f

[edadk]

It search for the license file

   Search path : /root/mosek/mosek.lic

So you are running the application as the user root. Not you installation claim your user name is user.

So you have mixed something up.

If you place the license file at

  /root/mosek/mosek.lic

it should work. However running applications at the root user is an EXTREMELY bad idea. 

I thought nobody would ever do that.

[p9g...@gmail.com]

I completely agree, but my matlab installtion does not run without root rights (I have no idea why)

[edadk]

So you when you put the license file where you are supposed to put, then does it work?

[p9g...@gmail.com]

Yes apart from this warning

I have output like this

>> mosekdiag
Matlab version: 8.3.0.532 (R2014a)
Architecture  : GLNXA64

[....]
mosekopt is working correctly.
Warning: MOSEK Fusion is not configured correctly; check that mosek.jar is added to the javaclasspath.
> In mosekdiag at 71

[edadk]

If you do not want to use MOSEK Fusion, then that is not a problem.

[p9g...@gmail.com]

OK thanks.

I also solved my problem with root permission (it was of course a problem with file rights), and so mosek is running fine (I deleted the mosek.lic from the root folder)

Thank you very much

[francis...@gmail.com]

Hi! I am having essentially the same problem, but for OSX. What should I do?

[Michal Adamaszek]

Could you please start a new thread with the details of your problem or write to our support. This one is too long and old.

[Ali Albattat]

My issue is having the following error when I run the MATLAB

Mosek error: MSK_RES_ERR_MISSING_LICENSE_FILE (A license cannot be located.)

[Michal Adamaszek]

That error means that the license file cannot be located.

In other words you have the license file in one place and Mosek expects it in another.

If you want to know where Mosek expects it, you can run the command "mosekdiag" in Matlab. You will find the path in the output.

Also, you can check out 

https://docs.mosek.com/latest/licensing/licensefaq.html#local-file-issues

https://docs.mosek.com/latest/licensing/client-setup.html#testing-and-debugging

Best,

Michal
