Here is a nice little website where you can download all the latest .ddl files for your PC. So in futre if your PC says cannot find .ddl blah blah for some software that you have downloaded then just search in the alphabetical list for the rquired .ddl folder and download for FREE

DLL-files.com - Download all your missing dll-files.

I've had plenty of issues in the past with .ddl files being corrupted and now I've found this website...Awesome
