I assume you are running older OS like WIN98? Maybe read this article:

i'm running winxp pro sp2 ...i had solve my problem after i search so many sites and this is the link http://www.dll-files.com/dllindex/pop.php?pncrt extract the files to c:/windows/system32 and paste

Never had issues with WINXP. I could have easily provided a link to replace the file you were missing. However, sometimes good to find the cause of the "real player" issue. Anyway, glad you got it resolved.
