After you placed and replaced all files and folders:
***************************************************************
*************************************************************************************

Open ReShade.ini with notepad or some other text editor and find these lines:

EffectSearchPaths=hard drive\game folder path\game .exe path\reshade-shaders-master\Shaders

TextureSearchPaths=hard drive\game folder path\game .exe path\reshade-shaders-master\Textures

PresetFiles=hard drive\game folder path\game .exe path\tru.ini

ScreenshotPath=hard drive\your screens path    -This's for the Screenshots by pressing - from num numbers of the keyboard! 
---------------------------------------------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------------------------------------------

You must find your game .exe path or where on your PC "reshade-shaders-master" and "tru.ini" file and folder are located!!!

For example, my gtaIV is located on D partition of my hard drive in gta4 folder so the lines must be like that:

EffectSearchPaths=D:\gta4\Grand Theft Auto IV\reshade-shaders-master\Shaders
TextureSearchPaths=D:\gta4\Grand Theft Auto IV\reshade-shaders-master\Textures
PresetFiles=D:\gta4\Grand Theft Auto IV\tru.ini

Also open ReShade.ini in EFLC(episodes from liberty city) and find and write the paths too!!! 

IF YOU DON'T DO THAT ReShade WILL NOT WORK!!!!!!!!!!!!!!!!!!!!!!

IF you have MXAO BUG!
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
You done everything and if your game looks like the "MXAO_BUG_EXAMPLE.png" this means that you have ambient
occlusion bug to fix it open ReShade.ini again and find these line:

PreprocessorDefinitions=RESHADE_DEPTH_LINEARIZATION_FAR_PLANE=1000.0,RESHADE_DEPTH_INPUT_IS_UPSIDE_DOWN=0,RESHADE_DEPTH_INPUT_IS_REVERSED=0,RESHADE_DEPTH_INPUT_IS_LOGARITHMIC=0

and make RESHADE_DEPTH_INPUT_IS_REVERSED=0  to   RESHADE_DEPTH_INPUT_IS_REVERSED=1  change 0 to 1!!!

if your game is normal then don't touch these line!!!!!
