Need help with making LastCo work

Ok so here's the problem: downloaded both clients; LastCO and the one that says update.(that's the way they are labeled on my desktop.)
I need help as to what i should do next because when i open the lastCO folder nothing happens...(literally.) post if you can help me.

Also to add...i know i have to somehow put/extract the update folder into LastCO..just isn't allowing me do that because when i open LastCo to paste the update folder in...nothing happens.

I could be doing it wrong, not great with computers..but anyone that can help i greatly appreciate it.

(Operating on Windows Vista)

I suggest you download Win.rar (free just google it) and when thats installed you simple right click on LastCO client and extract to LactCO\

Then you extract update to LastCO via "Extract Files" (find the folder with the search there) and click the folder then click extract.

That should do it, if no check the Server file (notepad file) matches with the one inside LastCO folder (go to LastCO inside of LastCO folder) the one not in LastCO>LastCO is correct so copy all that and past into the Server notepad file in the LastCO folder inside LastCO foler. Get it?

There is a guide in the guide section about installing the game. Please read the guide's before making more posts. :)

Thank you very much guys
