beny485 - I'm still pretty new at this, but I've made some progress with the help of the experienced modders above. Can you describe what you've done so far? if your posting here i assume you have the retail disc version of GTAV. Did you get LSPDFR 0.3 installed and running ok? Have you located the main folder where GTAV is installed? Have you downloaded OpenIV? The first link that TheDude posted above gives a very detailed tutorial on using OpenIV to locate and replace original files with modded files. I learned a couple of things from the guys in the thread above, and working with the latest version of OpenIV. First, it will create the "mods" folder for you, but the first time, you will have to show it where your GTAV folder is. second, it will warn you if the folder you navigated into in order to install modded files, had not yet been copied into the mods folder, and offer to copy it for you. Lastly, this new OpenIV didn't seem to like the drag and drop or the copy and paste method. I had to use the insert or + tool to navigate to the downloaded mmodified files and insert them into the correct spot in the mods folder (in edit mode). Hope this helps.
