打包后是不是只要把这些dll文件放在安装目录下面就可以了？需要放到system32下吗？

在vb工程里有这么两句申明语句，在工程的文件夹里有Sock.dll和STROPR.dll，请问是否要把这两个文件放到system32下，我不是很确定。请教各位。
Declare Function nWSockSndRcvData Lib "Sock.dll" (ByVal IP As String, ByVal PORT As Integer, ByVal sendBuf As Any, ByVal iSendLen As Integer, ByVal iRecvLen As Integer, ByVal wtime As Integer) As Integer

Declare Function nWStrOprStrToHex Lib "STROPR.DLL" (ByVal strTotalStr As String, ByVal strNewStr As String, ByVal intMax As Integer, ByVal intPos As Integer) As Integer
