Hey There!
I’d say that both pages have way too much going on to operate as effective Landing Pages. At the moment they are simply extended web pages like any other.
A Landing Page should have one specific aim or call to action – in this case to download the client software. At present the only download option is a small one top right and another text link at the bottom. I would recommend making these the focus of the whole page along with one, perhaps two other related messages, such as security, bonus – whatever.
By having all the other links around on the page your viewers have the chance to branch off and drift away from your stated aim.
