Matlab keeps asking for activation on Windows8

Hi,

I recently ended a trial and then upgraded to a student license for my PC.

However despite being able to activate successfully matlab keeps launching the activation module on startup.

I am using Windows 8. I have tried both online and offline activation.

The activation creates a .lic file which looks good.

I have tried also uninstalling and re-installing. Deleting the preferences etc.

Can you please help.

If you purchased the products in different version such as 2012a of Matlab(matlab 7.1) and 2012b of Simulink(matlab 8.0),

then , you need to get the license file for 2012a and not for 2012b.

If you download(or get) the license file for 2012b , you will get the license only for simmulink, so it will be not activated Matlab fully.

Someone reported a while ago that if they run the activation as Administrator then it worked permanently.

This worked for me!

Hello,

The activation module pops up the relvant UAC control when it runs and i permit it to make changes.

In addition i have tried to Run as Administrator using the normal method.

Thanks

Hi,

I found a soloution to the problem.

I can run Matlab from the command line with the -c option and then specify the path the license file.

matlab.exe -c "C:\Users\<username>\AppData\Roaming\MathWorks\MATLAB\R2015a_licenses\license_R2015a.lic"

(Matlab.exe still opens up the activation tool)

Thanks for the help anyway.
