Correct rtcdll.dll for MSN Msg 6 on XP?

[JW]

I am running XP home and have both MSN Msgr 6 (.602) and Win Msgr 5
installed.
I have rtcdll.dll
5.1.2600.1106 in my win/system32 directory
5.2.4949.1001 in my win/WinSxS/x86_Microsoft.Windows.Networking.RtcDll....
directory.
Are these the correct versions and are they in the correct folders?
