Hi,
In regard to the 'License Manager Error -25' you have encountered, following response by MathWorks Support Team could be helpful:
As stated in the article, this error occurs when you try to start a version of MATLAB that is newer than the version of the license.dat file on the license server. To resolve this issue, update the license.dat file on the server to the latest release that you are licensed for.
I hope the information provided above is helpful in resolving the issue.
