How do i use scripts,plugins ? 3ds max 2014

[allkarma]

Hi all, i have open iv and 3DS max 2014.

i have no idea how to import the GTA model into  3ds max.I can get as far as extracting the GTA model with open iv but that's about it !

I have seen the videos on youtube how to do it but all i can see is that the plugin or script is already running.

Could anyone give me a dummies guide on how to install or run whats needed to view in 3ds max please.

Many thanks everyone
