None of them! It replace the original MSN Messenger's Message Log's XSL file, that is to format the source XML log file into HTML format for display (Extensible Stylesheet Language, XSL). So you can see the new log just from the original build-in window! You can see the preview picture, it shows in the MSN Messenger's Message Log window! The transformation file is plain text so cannot be called a program. And it is complete no relation to Messenger Plus! How about install and feel the power of XML/XSL without program!
