Nokia Software

Can anyone tell me if I need to install some extra softwares in order for me to install and play n-gage games?
I have this game Worms World Party. After I unzipped it, a "system" folder appeared. I copied and pasted it into my memory card. I've checked and confirmed that the files were copied into the /apps and /libs folders. After that, I restarted my phone, but nothing came out. Does anybody know why is that?
I was wondering if I will need to install something else before I install those games. Cuz I just bought this N81, and this is my first time installing a n-gage game. Start preview still appears when I enter the n-gage folder.
Someone PLEASE help me!!!

I am also facing problem on my N81. The App, Lib,etc folders are extracted properly on the memory card. After disconnecting the USB. I get "INSTALLING' message. but soon after i get "Untrusted Application found on memory card. Go to Application Manager" message.

Plz help me out.

Copy the FIle to the memory card Root Directory . Then look for installation in the File Manager.That should do it. Else Get FExployer from www.gosynbian.com ,install it and then click on the file you want to install ,directly. If that does not work ,you do not have the file for the correct operating system ,ie;SYmbian ,the correct one.
