I just installed GTA 4 and I did everything necessary to make it run and it runs great. The problem is that I want to use the LCPDFR mod and when I use the auto installer, nothing happens when I press ALT-P. This is a fresh install. I have tried all of the guides I found online but what ends up happening when I follow them is either nothing,  What is a definitive step by step guide on how to do it? I don't want to mess up my install because I am crunched on time and I can't sit around and switch discs and wait for the re-installation. I don't know much about modding GTA 4 other than that you have to put certain files or script hooks into the GTA 4 folder. 

I would assume you’re using the latest version of complete edition and not a downgraded patch.

 

You will need the Compatibility Patch when using LCPDFR Legacy Edition.
