If you are receiving a segmentation fault error when attempting to start your newly installed Network License Manager it is most likely caused by corrupted files.

To resolve this issue, re-download the MATLAB installer and perform the license manager installation again. You can also try downloading the License Manager binaries from the following link and replace your existing lmutil, lmgrd, and mlm with the newly downloaded files.

MATLAB: Do I receive a “Host unreachable: connect” error when I use FOPEN of the TCP/IP object

This error is caused by a limitation of the Network layer and the Java Run-Time Environment in the Windows 98 and Windows NT 4.0 operating systems.

Enter a valid IP address from 0 to 255 in the dot-decimal format. For example:

t=tcpip('144.212.100.10');
