License hostID does not match license id

34 views (last 30 days)
License: 4Xxxxxxxx
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,
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
