Unable to change my folder attribute

Hi everyone, i've just want to ask or ask some help on how can i make my GTA IV directory folder set to a "Non Read Only" attribute permanently? I've always unchecked the box and applying the changes many times but after when i'm done and when i look on my folder properties again, my folder's read-only attribute was already checked although I've unchecked it. Do you think this was another reason why when I play GTA IV, have the LCPDFR installed, and exit my Safehouse in the game and after less than a minute the game crashes and didn't left any error message? That is why I don't know why it stops working. Are there anyone knows about this issue? I've always wanted to play LCPDFR everytime but due to my lack of knowledge in solving this kind problem and having technical problems on playing LCPDFR was making me sick.

Before unchecking the Attribute.

After applying all changes to the directory (and subdirectories).
