My problem was solved by installing of .Net 3.5 feature in my server

by going to server manager add/remove features

than I re run the prerequisite installer again and it worked

hope this will help other peoples facing same issue

Follow this Post. It works fine by renaming the ServerManager.exe to ServerManagerCMD.exe
