License Manager Error: -9

Hi,

I have received the follow message of error when I run Mathwork R2016b( you see the attachment).

ErroHow can I resolve this issue?

You appear to be executing as user name pasottip so you need to run the activation client and give that as the name to activate for.

（My computer use name is "Administrator", but "Administration" was input during my first activation, the License Manager Error: -9 appeared.）

Two stpes to solve this problem:

1. Find and run the active_matlab.exe
2. Input the right computer user name

@Jun Dong: "Administrator" sounds like you are working with admin privileges. This would be a bad idea. Example: You find some threads in this forum, in which users working with admin privileges have modified a toolbox function of Matlab by accident, such that Matlab could not be started anymore. It is much safer to work with limited user privileges.

Hello Enrico Astegiano,

I see that you are facing license related error while using MATLAB.

Please note that, with MATLAB releases R2012a through R2013b on Mac OS X 10.8 to at least 10.10 (Mountain Lion, Mavericks, and Yosemite), your MathWorks Host ID points to “en1”, not “en0”. On Mac OS X 10.7 and earlier, the Host ID is still “en0”.

This issue only affects Mac models which have multiple network interfaces. Macs without a built in Ethernet port are not affected. This includes the MacBook Air and the retina MacBook Pro.
