I barely managed to get MATLAB installed but I think it's installed correctly. However, when I cd to the bin directory and run ./matlab, the MATLAB logo comes up but then it instantly closes again and I get the error message:

License checkout failed. License Manager Error -2 

Make sure that the formatting of the license file is correct. When editing the license file use a basic text editor.
Troubleshoot this issue by visiting:

Diagnostic Information: Feature: MATLAB 

License path: /home/x/.matlab/R2012b_licenses:/home/x/MATLAB1/licenses/license.dat:/home/x/MATLAB1/licenses/network.lic 

Licensing error: -2,413. System Error: 2 ~/MATLAB1/bin$ ./matlab Fatal Error on startup: 

Cannot locate com/mathworks/jmi/OpaqueJavaInterface class

I've looked at the solution prescribed on the MathWorks website but I'm having a hard time figuring out what to do. I'm using 64 bit Ubuntu 12.10.

Does the license look ok when you go to the mentioned path? – Dennis Jaheruddin Feb 4 '13 at 13:14

Based on the error message, you should put the license file into the following folder

License path: /home/x/.matlab/R2012b_licenses:/home/x/MATLAB1/licenses/license.dat:/home/x/MATLAB1/licenses/network.lic

Those seem like many folders. Which one should I use? – user1282043 Sep 21 at 22:55
you can put it under /home/x/.matlab/ or /home/x/.matlab/R2012b_licenses The semi colon is just to separate many paths. – tndoan Sep 22 at 2:21

I solved this problem, by actually double checking that I had the right license. It turned out I had a different network.lic, and that's why my previous network.lic didn't work. I opened it up, and copied the same one another computer in the building had, and it worked fine.
