Gwx 3 Installation HELP

[Ritchie Rich]

I don't know if this is ment to go here but here goes...

I bought SH3 about 2 years ago for my laptop off steam and I've not stopped playing it since. I've always wanted this GWX3 mod but i'm not the greatest with computers and I have also I've read through forums and there is a lot of people who have problems installing it... so I put it off.

Bought a new pc a while ago and today I thought I'd have a go at getting this mod to work.
So I've installed the new copy off steam never played before on this pc. I've read that steam patches it to 1.4 and I've been on the game to check and it says 1.4 in the corner. I then downloaded the installation files it says It has detected mods but I have none. I've tried to move it to another file where the installation program is in and it says the same thing.

I'm confused and need your help!

Thanks a lot
