Oh, sorry!
PowerBible is a program you have to pay for, although its very cheap. (Actually, I didn't pay for my copy, a very nice person I met online sent me his copy when he learned I didn't have on)
It has 11 English Bibles (including the RSV) as ell as French, German andSpanish bibles.
The KJV has Strongs' definitions keyed to it.
It also has 3 Bible dictionaries, 7 topical bibles/sermon preparers (which I've found very useful), and commentaries by Matthew Henry, A Clarke, Wesley, Spurgeon, Barnes, Robertson and 8 others whose names I cannot recall right now.
Its my favourite, the one I use almost all the time. Its very easy to run, doesn't take up a lot of disk space, and you can unlock the NIV, NRSV and NASB if you want too. They also provide free updates which are very easy to use.
I'm not very good at working computer programs, which is why this was my first choice
Theophilos is a free program, and my favourite of the free ones.
It just has the KJV, as I recall, but its extremely easy to use. The main thing which recommends it to me is that you can get add-on, free modules created by users. For example - I have Vol1 of the Church Fathers' writings, Foxe's Book of Martyrs, the Westminster Confession, some of Anselm's writings, some of Augustines...that sort of thing. There are also all the usual dictionaries and commentaries available.
its just so easy to use

I found e-sword a bit difficult, as i recall, and one of them (I think it was called openbible?) I couldn't figure out in the least.
