Hello --

So I am not doing something right on installing of mods. Here is a link to a reddit post that has pictures of my file arrangements and a better description of the problem:

 

answer for 1)please be more specific....does it say something along the lines that "LSPDFR+ detected a newer version of LSPDFR use it at own risk"?if so than your fine it just means that you have im assuming LSPDFR 0.4 and the plugin is made for 0.3 which is still fine as i use this plugin and it works great for me

 

answer for 2

you put it in the wrong file im pretty sure its not the LSPDFR file in the plugins folder but the one in the GTA main file..where your ragehook and the gta.exe and all that fun stuff

C:\Program Files (x86)\Steam\steamapps\common\Grand Theft Auto V\lspdfr\audio\scanner

 

hope i helped
