On a Windows system, launch the "Programs and Features" (or equivalent, such as "Add or Remove Programs" on Windows XP) Control Panel utility and look for all installed IDL, ENVI or License Server items with the Publisher listed, for example, as"Exelis Visual Information Solutions,..." or "Exelis, Inc.", and then see the associated Version column information for that product.  For example, for the installed product, ENVI 5.3 SP1+IDL 8.5, here is the Program and Features control panel utility item details:

Also for the Exelis FlexLM License Server 8.5.1 installer, here are the Program and Features control panel utility item details:

Name: Network License Server
Publisher: Exelis Visual Information Solutions, Inc., a subsidiary of Harris Corporation
Product version: 8.5.1.0

Linux, Solaris, Mac OS X

On Linux, Solaris and Mac, you can determine the base product version installed through the name of the associated main IDL or ENVI product directory installed the machine.

On these platforms, the default product installation location depends on the version of IDL, ENVI associated with that product. Below are the default main product directories for IDL and corresponding ENVI products going back to IDL 8.0 and ENVI 4.8. The Exelis Products FlexLM License Server product version corresponds to the IDL version included with the installation.
