The person I spoke to at LLL said the $110 includes an Individual ( non
commercial use) license , a copy of the "Windows Executable" and the
manual to go with it
You can still get 4.2 if you want it $300 of an individual license, and
a copy of the "source code". You then I guess have to write you own GUI
and compile it or shell out $675 to W7EL net out of pocket $975
I ll probably spring for the $110 and hope the "windows executable" is
useful to us mere mortals

Was the cost of $110.00 the cost for the software or the cost of the manual?
I thought the software was much more.
