SAMP custom installer.... I forget who I got it from because I had the same problem when I reinstalled Windows 10.
topic here has the link: http://www.forum.convoytrucking.net/index.php?topic=54055.0    if the folder he needs is hidden, he either needs administrative access or make a checkmark by the 'show all folders' option and make sure SAMP can see the folder
