I have downloaded and ran a trial AE 2014. There is Eph:external text on a wheel. How it come with external ephimeris if AElite\EPH folder is empty on my PC?
You are right, a wheel label Eph:external means the external ephemerides have been used for calculating this specific chart.
You don't take into account that program is shipped with several precalculated and stored in charts.dat file charts that have been calculated on PC with external ephemeris installed.
If you recalculate all those charts with your program trial copy (Tools->Recalculate all charts) you will see the wheel table turned into Eph:internal.
