License manager installer reports invalid license

When installing version 2.6 or higher of the Intel® Software License Manager, it may report that the license file provided is invalid.  This can be caused by a mismatch in the hostname between the license file and OS.  The license file hostname must contain the entire value returned by running the hostname OS command.  

For example:

$ hostname
myhost.mydomain.com
$

The license file must contain myhost.domain.com.  If it only has myhost, then it will fail the validation check in the installer.
