ENVI runs on IDL so if you are launching ENVI+IDL, then look at the IDL Console in the IDLDE that launches for this information. For example, when I launch ENVI 5.1 +IDL, the IDL console shows the following at the top:
IDL Version 8.3, Microsoft Windows (Win32 x86_64 m64). (c) 2013, Exelis Visual Information Solutions, Inc.
IDL 7.0 would be associated with a pretty old version of ENVI - 4.5 from 2008.
