Hi,
In regard to the 'License Manager Error -38' you have encountered, following response by MathWorks Support Team could be helpful:
As stated in the article, the error indicates that either the username, hostname, or display is being prevented from using a product due to an EXCLUDE line in an options file. In order to resolve this error, you will need to be removed from the EXCLUDE list. Contact your License Administrator to have this change completed.
I hope the information provided above is helpful in resolving the issue.
