License: 4Xxxxxxxx

MATLAB & Simulink Student Version

After I changed the hard drive on my computer I can not run Matlab as it fails with -8 error.

The vol ID on computer is 80AF-1F68 but the license file shows 80AF1F68 ie the - is missing. When I try to edit the host ID in the Manually Activate Software on a Computer section it reverts to 80AF1F68

Hi Wiliam,

the license is connected to your harddrive. So if you copy the content of your harddrive on a new one, you have to deactivate the MATLAB license and reactivate it.

Follow that manual to deactivate MATLAB: Deactivate an Installation

and that one to reactivate it: Activate the Installation

If you have any trouble about that manipulation, you can contact the support (Contact Support)

Hi Nicolas,

Thanks for your prompt reply to my question. I did try to deactivate the installation and reactivate it. Hoever, I will try it again more carefully this time. It will be sometme before I have time to do it but I will report when I do it.

Thanks

Hi Nicolas,

I have been able to reinstall Matlab OK this time, I'm not sure what I did differently but it is now working again. Thanks
