Visual Studio C ++ MFC install DLLs

I wrote MFC Visual C++ program and use shared MFC dl.
So I need to redistribute the required DLLs and follow the two ways introduced in codeproject. Use dumpbin / DEPENDENTS  tool of VC6 to find the required DLLs and create install file with Inno Setup.
If the file is shared libraries, installing them in the System32 folder and set shared flag for that files.
If it's my private libraries. then installing them in the same folder of my project located.
