.dll files

When you are extracting files, you have been get the pop up of some .dll file has been missing. I too got this pop up message many times. Most of the time you will get this only when you are installing any games. When i was installing NFS shift i got error d3dx_91.dll file is missing. Below that some they instructed me to re install that file once again. After i searched for that .dll file in many sites. Most of the site advised me not to download that file in any sites. Also that told the reason and best way to get installed. First thing you need to check whether you have installed DIRECTX latest version. If you not having this directX latest then you will be having this problem. After i downloaded the latest direct X 11 from microsoft site i installed that. Now the problem is solved. So make sure you have all the requirements.
