I try and did everything I installed RPH RAGE Plugin Hook - 1.67.1242.15499 v1734. However I drag and drop everything in my gta folder the problem Im having is when I do everthing or click on properties to see if it has the block button nothing but once I click it I keep having the problem "Game Pathc Unsupported" What am Im doing wrong??

It says what the issue is, I am not sure how it can be made clearer. 

 

You have version 1604 of GTA V installed. The version of RPH you are using supports 1734. 

You'll need RAGEPluginHook 0.66 to use LSPDFR. This version isn't available anymore from the RAGE Plugin Hook website , so you'll need to use the version that comes with LSPDFR.

Those are not the problem I think the problem is it says "Destination Folder Access  Denied" "You need permission to perform this action" that's wat it keeps asking me
