I may have been wrong on this one. I checked my archive and the previously available version of EZNEC was EZWDemo60Inst.exe. The version currently being offered on the web site is EZNEC_Pro2_v6_setup.exe.
I have been using GAL-ANA and MMANA-GAL and definitely will be trying EZNEC. I wanted to try this one in the past but only the demo version was previously available.
