I am receiving a "not a valid key" error when installing on a Centos 7 machine using
$ ./install -inputFile installer_input.txt -agreeToLicense yes -silent yes
The install log below mentions a MATLAB Answer but doesn't give the URL. Please assist.

Answering my own question, I thought that supplying the license.dat file to fire up the network license manager was sufficient. Turns out I also needed to speciffy the file installation key in the installer_input.txt file as well. Once I did this, installation worked.
