I have a laptop that I installed LCPDFR and ELS v7, and also installed pro ELS vehicles, It works fine, but it's a laptop so it runs slow. I've installed GTA IV on a computer with xp and an NVIDIA graphics card and I have at least 2g of RAM. I did everything exactly the same as I did on my laptop but ELS doesn't work. I know how to set up ELS and install the vehicles. like I said. I did the exact same thing as I did when I installed it on my laptop, but the lights don't work, ELS menu doesn't pop up, and when I hit the default horn/siren button the siren turns on as if it was a default non ELS car. any help would be appreciated. thanks.

Did you remember to install a .asi loader like the modified dsound.dll or xliveless?

Is it a legal copy of the game you are running on your PC? 

Is it a legal copy of the game you are running on your PC? 

yes it is a legal copy of GTA IV.

And you are running it as administrator? 

okay i'll see what i can do Lieutenant Moody.

You do this by going to the GTA IV folder, right click on GTAIV.exe -> Properties -> Compatibility and select 'Run this program as administrator'. Do the same exact thing to the LaunchGTAIV.exe.

ELS does not open game here downloaded version 7 install all files and directories in your game does not open when I take els files open as normal what am I doing wrong?

Can you list the contents of your "scripts" and root folder?
