KMPlayer is unsupportive when playing video files

Hey,
When I try to play a video file in the KMplayer, I get an error message. Getting a bid scared of this error message ‘containing error’. I downloaded it from the authorized website after reading the reviews. Is any problem with the player? Do I need to uninstall the player? Whether this player might damage my system? Totally confused, please help me to solve this error.

C:Windowssystem32URL.DLL is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.
