A simple explanation of this:

the file open function probably returned a failure code, POVRay 
subsequently attempts to display an error message by going to windows to 
get the message for the return of GetLastError() [which gets the error 
code for the last operation]

"The operation completed successfully" is the text for error code 0 (no 
error)

Either of two things happened:

A) An operation between the error-causing function occured, clearing the 
last error.

B) The file open function somehow failed to set an error code.

[A] is much more likely, if a C Library function like fopen is used. it 
could have accidentally reset the error code by doing some cleanup.
