Hi, When I tried to activate my Matlab R2015a on my computer (OS Windows7), it went perfectly fine with this message "activation is complete". But when I try to run it, it asks me again to activate it. Can you help me please?

If you activate it again at the request, does that activate it and solve the problem or are you in an infinite loop?
If you keep getting the activation request and can’t launch MATLAB, Contact MathWorks Technical Support. Unfortunately, you’ll have to wait until the start of the next workday.

My pleasure.
You definitely have my sympathies!
The only interim solution I can think of is uninstall your current installation and to download and install it again and see if that solves the problem. That’s kludgy, inconvenient, and time-comsuming, but it could work. (No promises that it will.)

Hi, I have the same problem! I am running Windows 8.1, and I get an infinite loop when I try to activate (when I activate via login and confirm, the next time I run R2015a, I still get the activation prompt).
I have downloaded and re-installed and I get the same problem.
Is there any way to fix this? Thank you!

I was having a similar problem with a Student license with 64-bit Linux. I followed the suggestion above with some slight modifications and it solved the problem:
- Download the license.lic file from www.mathworks.com as mentioned above.
- Create a directory called licenses in the directory where MATLAB R2015a was installed. (i.e. /usr/local/MATLAB/R2015a)
- Copy the downloaded license.lic file to this folder (i.e. /usr/local/MATLAB/R2015a/licenses).
After this when I called sudo matlab from the command line, everything started up fine. (Note: my MATLAB is licensed to root).

To anyone looking to solve this problem who has used a MATLAB trial version: look in /usr/local/MATLAB/R2015a/licenses and delete any licenses that are "trial" versions, and copy in the license.lic.
