How can I activate Matlab R2015a?

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.

I'm indeed in an infinite loop. Thanks for your quick answer.

[Star Strider]

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.)

@Hugo:

Please post the solution MathWorks gave you! It will help others who look to this thread for help.

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 have contacted the support and they gave me an answer. But I'm really busy so I didn't do a thing for the moment. I can send you their answer if you want to test it.

Here is the answer from the support, i will test it later...

"Typically when the activation client continuously appears it is because there was an issue creating the license file on your machine. You can manually copy the file to the location. I see there were two activations on your license, you will need to determine which one is not working but running the following in a Command Prompt:

vol c:

This will provide you with the volume C serial number that we use as the host ID. Once you have this, login to your MathWorks account at www.mathworks.com select My Account, Manage Licenses and you should see your activations. To the right is a link to download your license file. Once you have this license file, save it to the following location:

C:\Program Files\MATLAB\R20XXx\Licenses

If there are other license files in that location you can delete them. If you cannot copy files to that location, the User Account Controls (UAC) may need to be disabled temporarily.

If after placing the file in this location you are still unable to launch MATLAB, please let know.

If you have any further questions, please do not hesitate to email me back. Please be sure to keep the REF ID included at the bottom of this email intact when replying to this message. If you have a new technical support question, please submit a new request here:

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:

1. Download the license.lic file from www.mathworks.com as mentioned above.
2. Create a directory called licenses in the directory where MATLAB R2015a was installed. (i.e. /usr/local/MATLAB/R2015a)
3. 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.
