When I try to download the setup file I get a message saying the file isn't a common file so it's flagged. Even after reporting it as safe, I still cannot open the setup.exe to start the install. Has anyone had this issue?

Download the manual install of LSPDFR. Drag and drop all of it's contents into your main directory of GTAV.

This is the newest portion of what I was looking for. I've tried to down load lspdfr on Xbox 1, Xbox Series X and even a PC. So I've essentially purchased this 3x in hope to just play this mod. But it keeps telling me Downloads not supported on XBox 1 and Series X. I've went and tried other browsers and I'm not getting any where. The other browsers don't even bring up the down load menu. What is the work around on this, it's the first time I've actually wanted to play a game, and I'm having extreme issues on this. Any help would be appreciated. 

LSPDFR is simply not compatible with any console. It only works on PC.
