I install the Matlab2009a to my computer successfully and when I try to activate it without using the internet (Activate manually without the Internet) and provide the path to license file. Then an error coming out
Could not complete Activation because the License File could not be written to disk. You might not have write permission on the License File or the folder. / home/ linyulin/ licenses/ license_ubuntu_161051_R2010a.lic See your System Administrator for assistance. The specific error message text is: / home/ linyulin/ licenses/ license_ubuntu_161051_R2010a.lic (Permission denied).
Thank you very much for your help. I'm really anxious about this problem because I have spent lots of time on this problem and really don't want to mass it up. Thank you again!
